*(this is just a scribbled draft, that's why it's still in German)*
### *Schema-F* für Permissions, Rollen und Grants
Permissions, Rollen und Grants werden in den INSERT/UPDATE/DELETE-Triggern von Geschäftsobjekten erzeugt und gelöscht. Das Löschen erfolgt meistens automatisch über das zugehörige RbacObject, die INSERT- und UPDATE-Trigger müssen jedoch in *pl/pgsql* ausprogrammiert werden.
Das folgende Schema soll dabei unterstützen, die richtigen Permissions, Rollen und Grants festzulegen.
An einigen Stellen ist vom *Initiator* die Rede. Als *Initiator* gilt derjenige User, der die Operation (INSERT oder UPDATE) durchführt bzw. eine explizit anzugebende Rolle des Users.
Wird keine solche explizite Rolle angegeben, gilt die granted Rolle als diejenige, als der das Grant erfolgt.
#### Typ Root: Objekte, welche nur eine Spezialisierung bzw. Zusatzdaten für andere Objekte bereitstellen (z.B. Partner für Relations vom Typ Partner oder Partner Details für Partner)
Objektorientiert gedacht, enthalten solche Objekte die Zusatzdaten einer Subklasse; die Daten im Partner erweitern also eine Relation vom Typ `partner`.
- Dann muss dieses Objekt zeitlich nach dem Objekt erzeugt werden, auf dass es sich bezieht, also z.B. zeitlich nach der Relation.
- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
- Es werden **keine** Rollen für dieses Objekt erzeugt.
- Statt eigener Rollen werden die o.g. Permissions passenden Rollen des Hauptobjekts zugewiesen (granted) bzw. aus denen entfernt (revoked).
- Handelt es sich um Zusatzdaten zum Zwecke der Spezialisierung, dann z.B. so:
- Delete (\*) <-- Owner des Hauptobjektes
- Edit <-- **Admin** des Hauptobjektes
- View <-- Agent des Hauptobjektes
- Handelt es sich um Zusatzdaten, für die sich Edit-Rechte delegieren lassen sollen (wie im Falle der Partner-Details eines Partners), dann z.B. so:
- Delete (\*) <-- Owner des Hauptobjektes
- Edit <-- **Agent** des Hauptobjektes
- View <-- Agent des Hauptobjektes
- Für die Rollenzuordnung zwischen referenzierten Objekten gilt:
- Für Objekte vom Typ Root werden die Rollen des zugehörigen Aggregator-Objektes verwendet.
- Gibt es Referenzen auf hierarchisch verbundene Objekte (z.B. Debitor.refundBankAccount) gilt folgende Faustregel:
***Nach oben absteigen, nach unten halten oder aufsteigen.*** An einem fachlich übergeordneten Objekt wird also eine niedrigere Rolle (z.B. Debitor.ADMIN -> Partner.AGENT), einem fachlich untergeordneten Objekt eine gleichwertige Rolle (z.B. Partner.ADMIN -> Debitor.ADMIN) zugewiesen oder sogar aufgestiegen (Debitor.ADMIN -> Package.TENANT).
- Für Referenzen zwischen Objekten, die nicht hierarchisch zueinander stehen (z.B. Debitor und Bankverbindung), wird auf beiden seiten abgestiegen (also Debitor.ADMIN -> BankAccount.REFERRER und BankAccount.ADMIN -> Debitor.TENANT).
Anmerkung: Der Typ-Begriff *Root* bezieht sich auf die Rolle im fachlichen Datenmodell. Im Bezug auf den Teilgraphen eines fachlichen Kontexts ist dies auch eine Wurzel im Sinne der Graphentheorie. Aber in anderen fachlichen Kontexten können auch diese Objekte von anderen Teilgraphen referenziert werden und werden dann zum inneren Knoten.
#### Typ Aggregator: Objekte, welche weitere Objekte zusammenfassen (z.B. Relation fasst zwei Persons und einen Contact zusammen)
Solche Objekte verweisen üblicherweise auf Objekte vom Typ Leaf und werden oft von Objekten des Typs Root referenziert.
- Es werden i.d.R. folgende Rollen für diese Objekte erzeugt:
- Owner, Admin, Agent, Tenent(, Guest?)
- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
- Die Permissions werden den Rollen sinnvoll zugewiesen, z.B.:
- Owner -> Delete (\*)
- Admin --> Edit
- Tenant (oder ggf. Guest) --> View
- Außerdem werden folgende Grants erstellt bzw. entzogen:
- Initiator --> Owner
- Owner --> Admin
- Admin --> Referrer
- Admins der referenzierten Objekte werden Agent des Aggregators
- Tenants des Aggregators werden Referrer der referenzierten Objekte
### Typ Leaf: Handelt es sich um ein Objekt, welches (außer zur Modellierung separater Permissions) keine Unterobjekte enthält (z.B. Person, Customer)?
Solche Objekte werden üblicherweise von Objekten des Typs Aggregator, manchmal auch von Objekten des Typs Root, referenziert.
- Es werden i.d.R. folgende Rollen für diese Objekte erzeugt:
- Owner, Admin, Referrer
- Es werden Delete (\*), Edit und View Permissions für dieses Objekt erzeugt.
- Die Permissions werden den Rollen sinnvoll zugewiesen, z.B.:
- Delete (\*) <-- Owner
- Edit <-- Admin
- View <-- Referrer
- Außerdem werden folgende Grants erstellt bzw. entzogen:
- Owner --> Admin
- Admin --> Referrer

(this is just a scribbled idea, that's why it's still in German)
Ich habe mal wieder vom RBAC-System geträumt 🙈 Ok, im Halbschlaf darüber nachgedacht trifft es wohl besser. Und jetzt frage ich mich, ob wir viel zu kompliziert gedacht haben.
Bislang gingen wir ja davon aus, dass, wenn komplexe Entitäten (z.B. Partner) erzeugt werden, wir wir über den INSERT-Trigger den Rollen der verknüpften Entitäten (z.B. den Rollen der Personendaten des Partners) auch Rechte an den komplexeren Entitäten und umgekehrt geben müssen.
Da die komplexen Entitäten nur mit gewissen verbundenen Entitäten überhaupt sinnvoll nutzbar sind und diese daher über INNSER JOINs mitladen, könnte sonst auch nur jemand diese Entitäten, der auch die SELECT-Permission an den verküpften Entitäten hat.
Vor einigen Wochen hatten wir schon einmal darüber geredet, ob wir dieses Geflecht wirklich komplett durchplanen müssen, also über mehrere Stufen hinweg, oder ob sehr warscheinlich eh dieselben Leuten an den weiter entfernten Entitäten die nötien Rechte haben, weil dahinter dieselben User stehen. Also z.B. dass gewährleistet ist, dass jemand mit ADMIN-Recht an den Personendaten des Partners auch bis in die SEPA-Mandate eines Debitors hineinsehen kann.
Und nun gehe ich noch einen Schritt weiter: Könnte es nicht auch andersherum sein? Also wenn jemand z.B. SELECT-Recht am Partner hat, dass wir davon ausgehen können, dass derjenige auch die Partner-Personen- und Kontaktdaten sehen darf, und zwar implizit durch seine Partner-SELECT-Permission und ohne dass er explizit Rollen für diese Partner-Personen oder Kontaktdaten inne hat?
Im Halbschlaf kam mir nur die Idee, warum wir nicht einfach die komplexen JPA-Entitäten zwar auf die restricted View setzen, wie bisher, aber für die verknüpften Entitäten auf die direkten (bisher "Raw..." genannt) Entitäten gehen. Dann könnte jemand mit einer Rolle, welche die SELECT-Permission auf die komplexe JPA-Entität (z.B.) Partner inne hat, auch die dazugehörige Relation(ship) ["Relation" wurde vor kurzem auf kurz "Relation" umbenannt] und die wiederum dazu gehörigen Personen- und Kontaktdaten lesen, ohne dass in einem INSERT- und UPDATE-Trigger der Partner-Entität die ganzen Grants mit den verknüpften Entäten aufgebaut und aktualisiert werden müssen.
Beim Debitor ist das nämlich selbst mit Generator die Hölle, zumal eben auch Querverbindungen gegranted werden müssen, z.B. von der Debitor-Person zum Sema-Mandat - jedenfalls wenn man nicht Gefahr laufen wollte, dass jemand mit Admin-Rechten an der Partner-Person (also z.B. ein Repräsentant des Partners) die Sepa-Mandate der Debitoren gar nicht mehr sehen kann. Natürlich bräuchte man immer noch die Agent-Rolle am Partner und Debitor (evtl. repräsentiert durch die jeweils zugehörigen Relation - falls dieser Trick überhaupt noch nötig wäre), sowie ein Grant vom Partner-Agent auf den Debitor-Agent und vom Debitor-Agent auf die Sepa-Mandate-Admins, aber eben ohne filigran die ganzen Neben-Entäten (Personen- und Kontaktdaten von Partner und Debitor sowie Bank-Account) in jedem Trigger berücksichtigen zu müssen. Beim Refund-Bank-Account sogar besonders ätzend, weil der optional ist und dadurch zig "if ...refundBankAccountUuid is not null then ..." im Code enstehen (wenn der auch generiert ist).
Mit anderen Worten, um als Repräsentant eines Geschäftspartners auf den Bank-Account der Sepa-Mandate sehen zu dürfen, wird derzeut folgende Grant-Kette durchlaufen (bzw. eben noch nicht, weil es noch nicht funktioniert):
User -> Partner-Holder-Person:ADMIN -> Partner-Relation:AGENT -> Debitor-Relation:AGENT -> Sepa-Mandat:ADMIN -> BankAccount:ADMIN -> BankAccount:SELECT
Daraus würde:
User -> Partner-Relation:AGENT -> Debitor-Relation:AGENT -> Sepa-Mandat:ADMIN -> Sepa-Mandat:SELECT*
(*mit JOIN auf RawBankAccount, also implizitem Leserecht)
Das klingt zunächst nach nur einer marginalen Vereinfachung, die eigentlich Vereinfachung liegt aber im Erzeugen der Grants in den Triggern, denn da sind zudem noch Partner-Anchor-Person, Debitor-Holder- und Anchor-Person, Partner- und Debitor-Contact sowie der RefundBankAccount zu berücksichtigen. Und genau diese Grants würden großteils wegfallen, und durch implizite Persmissions über die JOINs auf die Raw-Tables ersetzt werden. Den refundBankAccound müssten wir dann, analog zu den Sepa-Mandataten, umgedreht modellieren, da den sonst
Man könnte das Ganze auch als "Entwicklung der Rechtestruktur für Hosting-Entitäten auf der obersten Ebene" (Manged Webspace, Managed Server, Cloud Server etc.) sehen, denn die hängen alle unter dem Mega-komplexen Debitor.

# RBAC Performance Analysis
This describes the analysis of the legacy-data-import which took way too long, which turned out to be a problem in the RBAC-access-rights-check as well as `EntityManager.persist` creating too many SQL queries.
## Our Performance-Problem
During the legacy data import for hosting assets we noticed massive performance problems. The import of about 2200 hosting-assets (IP-numbers, managed-webspaces, managed- and cloud-servers) as well as the creation of booking-items and booking-projects as well as necessary office-data entities (persons, contacts, partners, debitors, relations) **took 25 minutes**.
Importing hosting assets up to UnixUsers and EmailAddresses even **took about 100 minutes**.
(The office data import sometimes, but rarely, took only 10min.
We could not find a pattern, why that was the case. The impression that it had to do with too many other parallel processes, e.g. browser with BBB or IntelliJ IDEA was proved wrong, but stopping all unnecessary processes and performing the import again.)
## Preparation
### Configuring PostgreSQL
The pg_stat_statements PostgreSQL-Extension can be used to measure how long queries take and how often they are called.
The module auto_explain can be used to automatically run EXPLAIN on long-running queries.
To use this extension and module, we extended the PostgreSQL-Docker-image:
```Dockerfile
FROM postgres:15.5-bookworm
RUN apt-get update && \
apt-get install -y postgresql-contrib && \
apt-get clean
COPY etc/postgresql-log-slow-queries.conf /etc/postgresql/postgresql.conf
```
And create an image from it:
```sh
docker build -t postgres-with-contrib:15.5-bookworm .
```
Then we created a config file for PostgreSQL in `etc/postgresql-log-slow-queries.conf`:
```
shared_preload_libraries = 'pg_stat_statements,auto_explain'
log_min_duration_statement = 1000
log_statement = 'all'
log_duration = on
pg_stat_statements.track = all
auto_explain.log_min_duration = '1s' # Logs queries taking longer than 1 second
auto_explain.log_analyze = on # Include actual run times
auto_explain.log_buffers = on # Include buffer usage statistics
auto_explain.log_format = 'json' # Format the log output in JSON
listen_addresses = '*'
```
And a Docker-Compose config in 'docker-compose.yml':
```
version: '3.8'
services:
postgres:
image: postgres-with-contrib:15.5-bookworm
container_name: custom-postgres
environment:
POSTGRES_PASSWORD: password
volumes:
- /home/mi/Projekte/Hostsharing/hsadmin-ng/etc/postgresql-log-slow-queries.conf:/etc/postgresql/postgresql.conf
ports:
- "5432:5432"
command:
- bash
- -c
- >
apt-get update &&
apt-get install -y postgresql-contrib &&
docker-entrypoint.sh postgres -c config_file=/etc/postgresql/postgresql.conf
```
### Activate the pg_stat_statements Extension
The pg_stat_statements extension was activated in our Liquibase-scripts:
```
create extension if not exists "pg_stat_statements";
```
### Running the Tweaked PostgreSQL
Now we can run PostgreSQL with activated slow-query-logging:
```shell
docker-compose up -d
```
### Running the Import
Using an environment like this:
```shell
export HSADMINNG_POSTGRES_JDBC_URL=jdbc:postgresql://localhost:5432/postgres
export HSADMINNG_POSTGRES_ADMIN_USERNAME=postgres
export HSADMINNG_POSTGRES_ADMIN_PASSWORD=password
export HSADMINNG_POSTGRES_RESTRICTED_USERNAME=restricted
export HSADMINNG_SUPERUSER=superuser-alex@hostsharing.net
```
We can now run the hosting-assets-import:
```shell
time gw-importHostingAssets
```
### Fetch the Query Statistics
And afterward we can query the statistics in PostgreSQL, e.g.:
```SQL
WITH statements AS (
SELECT * FROM pg_stat_statements pss
)
SELECT calls,
total_exec_time::int/(60*1000) as total_mins,
mean_exec_time::int as mean_millis,
query
FROM statements
WHERE calls > 100 AND shared_blks_hit > 0
ORDER BY total_exec_time DESC
LIMIT 16;
```
### Reset the Query Statistics
```SQL
SELECT pg_stat_statements_reset();
```
## Analysis Result
### RBAC-Access-Rights Detection query
This CTE query was run over 4000 times during a single import and takes in total the whole execution time of the import process:
```SQL
WITH RECURSIVE grants AS (
SELECT descendantUuid, ascendantUuid, $5 AS level
FROM RbacGrants
WHERE assumed
AND ascendantUuid = any(subjectIds)
UNION ALL
SELECT g.descendantUuid, g.ascendantUuid, grants.level + $6 AS level
FROM RbacGrants g
INNER JOIN grants ON grants.descendantUuid = g.ascendantUuid
WHERE g.assumed
),
granted AS (
SELECT DISTINCT descendantUuid
FROM grants
)
SELECT DISTINCT perm.objectUuid
FROM granted
JOIN RbacPermission perm ON granted.descendantUuid = perm.uuid
JOIN RbacObject obj ON obj.uuid = perm.objectUuid
WHERE (requiredOp = $7 OR perm.op = requiredOp)
AND obj.objectTable = forObjectTable
LIMIT maxObjects+$8
```
That query is used to determine access rights of the currently active RBAC-subject(s).
We used `EXPLAIN` with a concrete version (parameters substituted with real values) of that query and got this result:
```
QUERY PLAN

### Office-Relation-Query
```SQL
SELECT hore1_0.uuid,a1_0.uuid,a1_0.familyname,a1_0.givenname,a1_0.persontype,a1_0.salutation,a1_0.title,a1_0.tradename,a1_0.version,c1_0.uuid,c1_0.caption,c1_0.emailaddresses,c1_0.phonenumbers,c1_0.postaladdress,c1_0.version,h1_0.uuid,h1_0.familyname,h1_0.givenname,h1_0.persontype,h1_0.salutation,h1_0.title,h1_0.tradename,h1_0.version,hore1_0.mark,hore1_0.type,hore1_0.version
FROM hs_office_relation_rv hore1_0
LEFT JOIN hs_office_person_rv a1_0 ON a1_0.uuid=hore1_0.anchoruuid
LEFT JOIN hs_office_contact_rv c1_0 ON c1_0.uuid=hore1_0.contactuuid
LEFT JOIN hs_office_person_rv h1_0 ON h1_0.uuid=hore1_0.holderuuid
WHERE hore1_0.uuid=$1
```
That query on the `hs_office_relation_rv`-table joins the three references anchor-person, holder-person and contact.
### Total-Query-Time > Total-Import-Runtime
That both queries total up to more than the runtime of the import-process is most likely due to internal parallel query processing.
## Attempts to Mitigate the Problem
### VACUUM ANALYZE
In the middle of the import, we updated the PostgreSQL statistics to recalibrate the query optimizer:
```SQL
VACUUM ANALYZE;
```
This did not improve the performance.
### Improving Joins + Indexes
We were suspicious about the sequential scan over all `rbacpermission` rows which was done by PostgreSQL to execute a HashJoin strategy. Turning off that strategy by
```SQL
ALTER FUNCTION queryAccessibleObjectUuidsOfSubjectIds SET enable_hashjoin = off;
```
did not improve the performance though. The HashJoin was actually still applied, but no full table scan anymore:
```
[...]
QUERY PLAN
-> Hash Join (cost=36.02..40.78 rows=1 width=16)
Hash Cond: (grants.descendantuuid = perm.uuid)
-> HashAggregate (cost=13.32..15.32 rows=200 width=16)
Group Key: grants.descendantuuid
-> CTE Scan on grants (cost=0.00..11.84 rows=592 width=16)
[...]
```
The HashJoin strategy could be great if the hash-map could be kept for multiple invocations. But during an import process, of course, there are always new rows in the underlying table and the hash-map would be outdated immediately.
Also creating indexes which should suppor the RBAC query, like the following, did not improve performance:
```SQL
create index on RbacPermission (objectUuid, op);
create index on RbacPermission (opTableName, op);
```
### LAZY loading for Relation.anchorPerson/.holderPerson/

Now, finally, the total runtime of the import was down to 12 minutes. This is repeatable, where originally, the import took about 25mins in most cases and just rarely - and for unknown reasons - 10min.
### Importing UnixUser and EmailAlias Assets
But once UnixUser and EmailAlias assets got added to the import, the total time went up to about 110min.
This was not acceptable, especially not, considering that domains, email-addresses and database-assets are almost 10 times that number and thus the import would go up to over 1100min which is 20 hours.
In a first step, a `HsHostingAssetRawEntity` was created, mapped to the raw table (hs_hosting_asset) not to the RBAC-view (hs_hosting_asset_rv). Unfortunately we did not keep measurements, but that was only part of the problem anyway.
The main problem was, that there is something strange with persisting (`EntityManager.persist`) for EmailAlias assets. Where importing UnixUsers was mostly slow due to RBAC SELECT-permission checks, persisting EmailAliases suddenly created about a million (in numbers 1.000.000) SQL UPDATE statements after the INSERT, all with the same data, just increased version number (used for optimistic locking). We were not able to figure out why this happened.
Keep in mind, it's the same table with the same RBAC-triggers, just a different value in the type column.
Once `EntityManager.persist` was replaced by an explicit SQL INSERT - just for `HsHostingAssetRawEntity`, the total time was down to 17min. Thus importing the UnixUsers and EmailAliases took just 5min, which is an acceptable result. The total import of all HostingAssets is now estimated to about 1 hour (on my developer laptop).
Now, the longest running queries are these:
| No.| calls | total_m | mean_ms | query |
|---:|---------|--------:|--------:|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

| 8 | 497 | 2 | 255 | select hope1_0.uuid,hope1_0.familyname,hope1_0.givenname,hope1_0.persontype,hope1_0.salutation,hope1_0.title,hope1_0.tradename,hope1_0.version from public.hs_office_person_rv hope1_0 where hope1_0.uuid=$1 |
| 9 | 13.144 | 1 | 8 | SELECT createRoleWithGrants( hsHostingAssetTENANT(NEW), permissions => array[$7], incomingSuperRoles => array[ hsHostingAssetAGENT(NEW), hsOfficeContactADMIN(newAlarmContact)], outgoingSubRoles => array[ hsBookingItemTENANT(newBookingItem), hsHostingAssetTENANT(newParentAsset)] ) |
| 10 | 13.144 | 1 | 5 | SELECT createRoleWithGrants( hsHostingAssetADMIN(NEW), permissions => array[$7], incomingSuperRoles => array[ hsBookingItemAGENT(newBookingItem), hsHostingAssetAGENT(newParentAsset), hsHostingAssetOWNER(NEW)] ) |
That the `INSERT into hs_hosting_asset` (No. 1) takes up the most time, seems to be normal, and 21ms for each call is also fine.
It seems that the trigger effects (eg. No. 3 and No. 4) are included in the measure for the causing INSERT, otherwise summing up the totals would exceed the actual total time of the whole import. And it was to be expected that building the RBAC rules for new business objects takes most of the time.
In production, the `SELECT ... FROM hs_office_relation_rv` (No. 2) with about 0.5 seconds could still be a problem. But once we apply the improvements from the hosting asset area also to the office area, this should not be a problem for the import anymore.
## Further Options To Explore
1. Instead of separate SQL INSERT statements, we could try bulk INSERT.
2. We could use the SQL INSERT method for all entity-classes, or at least for all which have high row counts.
3. For the production code, we could use raw-entities for referenced entities, here usually RBAC SELECT permission is given anyway.
## The Problematically Huge Join
The origin problem was the expensive RBAC check for many SELECT queries.
This consists of two parts:
1. The recursive CTE query to determine which object's UUIDs are visible for the current subject.
This query itself takes currently about 250ms thus is no problem by itself as long as we only need it once per request.
2. Joining the result from 1. with the result if a business query.
The performance of the business query itself is no problem, for the join see the following explanations.
Superusers can see all objects (currently already over 90.000)
and even high level roles of customers with many hosting assets can see several thousand objects.
This is the one side of that problematic join.
The other side of that problematic is the result of the business query.
For example if a user wants to select all of their e-mail-addresses, that might easily half of the visible objects.
Thus, we would have a join of for example 5.000 x 2.500 rows, which is going to be slow.
As there are currently about 84.000 objects are hosting assets and 33.000 e-mail-addresses in our system,
for a superuser we would even run into an 84.0000 x 33.0000 join.
We found some solution approaches:
1. Getting rid of the `rbacrole` and `rbacpermission` table and only having implicit roles with implicit grants (OWNER->ADMIN->AGENT->TENENT->REFERRER) by comparison of ordered enum values and fixed permission assignments (e.g. OWENER->DELETE, ADMIN->UPDATE etc.). We could also get rid of the table `rbacreferece` if we enter users as business objects.
This should dramatically reduce the size of the table `rbackgrant` as well as the recusion levels.
But since we only apply this query once for each business query, that would only improve performance once we have way more objects in our system, but does not help our current problem.
It's quite some effort to implement even just a prototype, so we did not further explore this idea.
2. Adding the object type to the table `rbacObject` to reduce the size of the result of the recursive CTE query.
See chapter below.
3. Inverting the recursion of the CTE-query, combined with the type condition.
Instead of starting the recursion with `currentsubjectsuuids()`,
we could start it with the target table name and row-type,
then recurse down to the `currentsubjectsuuids()`.
In the end, we need the object UUIDs, though.
But if we start with the join of `rbacObject` with `rbacPermission`,
we need to forward the object UUIDs through the whole recursion.
This idea was not yet further explored.
### Adding The Object Type To The Table `rbacObject`
This optimization idea came from Michael Hierweck and was promising.
The idea is to reduce the size of the result of the recursive CTE query and maybe even speed up that query itself.
To evaluate this, I added a type column to the `rbacObject` table, initially as an enum hsHostingAssetType. Then I entered the type there for all rows from hs_hosting_asset. This means that 83,886 of 92,545 rows in `rbacobject` have a type set, leaving 8,659 without.
If we do this for other types (we currently have 1,271 relations and 927 booking items), it gets more complicated because they are different enum types. As varchar(16), we could lose performance again due to the higher storage space requirements.
But the performance gained is not particularly high anyway.
See the average seconds per recursive CTE select as role 'hs_hosting_asset:<DEBITOR>defaultproject:ADMIN',
joined with business query for all `'EMAIL_ADDRESSES'`:
| | D-1000000-hsh | D-1000300-mih |
|-----------------------------------------------------|------------------|---------------|
| currently (without type comparision in rbacobject): | ~3.30 - ~3.49 | ~0.23 |
| optimized (with type comparision in rbacobject): | ~2.99 - ~3.08 | ~0.21 |
As you can see, the query is no problem at all for normal customers (in the example, yours truly). With Hostsharing (D-1000000-hsh) it is quite slow.
Luckily this experiment also shows that it's not a big problem, having all hosting assets in the same database table.
Implementing this approach would be a bit difficult anyway, because we would need to transfer the type query parameter into the definition of the restricted view. We have not even the slightest idea how this could be done.
See the related queries in [recursive-cte-experiments-for-accessible-uuids.sql](../sql/recursive-cte-experiments-for-accessible-uuids.sql). They might have changed independently since this document was written, but you can still check out the old version from git.
### Rearranging the Parts of the CTE-Query
I also moved the function call which determines into its own WITH-section, with no improvement.
Experimentally I moved the business condition into the CTE SELECT, also with no improvement.
Such rearrangements seem to be successfully done by the PostgreSQL query optimizer.
## Summary
### What we did Achieve?
In a first step, the total import runtime for office entities was reduced from about 25min to about 10min.
In a second step, we reduced the import of booking- and hosting-assets from about 100min (not counting the required office entities) to 5min.
### What did not Help?
Rearranging the CTE query by extracting parts into WITH-clauses did not improve the performance.
Surprisingly little performance gain (<10% improvement) came from reducing the result of the CTE query by moving the hosting asset type into RBAC-system and using it in the inner SELECT query instead of in the outer SELECT query of the application side.
### What did Help?
Merging the recursive CTE query to determine the RBAC SELECT-permission, made it more clear which business-queries take the time.
Avoiding EAGER-loading where not necessary, reduced the total runtime of the import to about the half.
The major improvement came from using direct INSERT statements, which avoided some SELECT statements unnecessarily generated by the EntityManager and also completely bypassed the RBAC SELECT permission checks.
### What Still Has To Be Done?
Where this performance analysis was mostly helping the performance of the legacy data import, we still need measures and improvements for the productive code.
For sure, using more LAZY-loading also helps in the production code. For some more ideas see section _Further Options To Explore_.

E.g. for a new *customer* it would be granted to 'administrators' and for a new *package* to the 'customer#...:ADMIN'.
Whoever has the owner-role assigned can do everything with the related business-object, including deleting (or deactivating) it.
In most cases, the permissions to other operations than 'delete' are granted through the 'admin' role.
In most cases, the permissions to other operations than 'DELETE' are granted through the 'admin' role.
By this, all roles ob sub-objects, which are assigned to the 'admin' role, are also granted to the 'owner'.
#### admin
#### ADMIN
The admin-role is granted to a role of those subjects who manage the business object.
E.g. a 'package' is manged by the admin of the customer.
Whoever has the admin-role assigned, can usually edit the related business-object but not deleting (or deactivating) it.
Whoever has the admin-role assigned, can usually update the related business-object but not delete (or deactivating) it.
The admin-role also comprises lesser roles, through which the view-permission is granted.
The admin-role also comprises lesser roles, through which the SELECT-permission is granted.
#### agent
#### AGENT
The agent-role is not used in the examples of this document, because it's for more complex cases.
It's usually granted to those roles and users who represent the related business-object, but are not allowed to edit it.
It's usually granted to those roles and users who represent the related business-object, but are not allowed to update it.
Other than the tenant-role, it usually offers broader visibility of sub-business-objects (joined entities).
E.g. a package-admin is allowed to see the related debitor-business-object,
but not its banking data.
#### tenant
#### TENANT
The tenant-role is granted to everybody who needs to be able to view the business-object and (probably some) related business-objects.
The tenant-role is granted to everybody who needs to be able to select the business-object and (probably some) related business-objects.
Usually all owners, admins and tenants of sub-objects get this role granted.
Some business-objects only have very limited data directly in the main business-object and store more sensitive data in special sub-objects (e.g. 'customer-details') to which tenants of sub-objects of the main-object (e.g. package admins) do not get view permission.
Some business-objects only have very limited data directly in the main business-object and store more sensitive data in special sub-objects (e.g. 'customer-details') to which tenants of sub-objects of the main-object (e.g. package admins) do not get SELECT permission.
#### guest
#### GUEST
(Deprecated)
#### REFERRER
Like the agent-role, the guest-role too is not used in the examples of this document, because it's for more complex cases.
If the guest-role exists, the view-permission is granted to it, instead of to the tenant-role.
Other than the tenant-role, the guest-roles does never grant any roles of related objects.
If the referrer-role exists, the SELECT-permission is granted to it, instead of to the tenant-role.
Other than the tenant-role, the referrer-roles does never grant any roles of related objects.
Also, if the guest-role exists, the tenant-role receives the view-permission through the guest-role.
Also, if the referrer-role exists, the tenant-role receives the SELECT-permission through the referrer-role.
