-## Biggest Flaws in our Architecture
-
-### The RBAC System is too Complicated
-
-Now, where we have a better experience with what we really need from the RBAC system, we have learned
-that and creates too many (grant- and role-) rows and too even tables which could be avoided completely.
-
-The basic idea is always to always have a fixed set of ordered role-types which apply for all DB-tables under RBAC,
-e.g. OWNER>ADMIN>AGENT\[>PROXY?\]>TENENT>REFERRER.
-Grants between these for the same DB-row would be implicit by order comparision.
-This way we would get rid of all explicit grants within the same DB-row
-and would not need the `rbac.role` table anymore.
-We would also reduce the depth of the expensive recursive CTE-query.
-
-This has to be explored further.
-For now, we just keep it in mind and  
-
-### The Mapper is Error-Prone
-
-Where `org.modelmapper.ModelMapper` reduces bloat-code a lot and has some nice features about recursive data-structure mappings,
-it often causes strange errors which are hard to fix.
-E.g. the uuid of the target main object is often taken from an uuid of a sub-subject.
-(For now, use `StrictMapper` to avoid this, for the case it happens.)

-# Handling Automatic Creation of Hosting Assets for New Booking Items
-
-**Status:**
-- [x] proposed by (Michael Hönnig)
-- [ ] accepted by (Participants)
-- [ ] rejected by (Participants)
-- [ ] superseded by (superseding ADR)
-
-
-## Context and Problem Statement
-
-When a customer creates a new booking item (e.g., `MANAGED_WEBSPACE`), the system must automatically create the related hosting asset.
-This process can sometimes fail or require additional data from the user, e.g. installing a DNS verification key, or a hostmaster, e.g. the target server to use.
-
-The challenge is how to handle this automatic creation process while dealing with missing data, asynchronicity and failures while ensuring system consistency and proper user notification.
-
-
-### Technical Background
-
-The creation of hosting assets can occur synchronously (in simple cases) or asynchronously (when additional steps like manual verification are needed).
-For example, a `DOMAIN_SETUP` hosting asset may require DNS verification from the user, and until this is provided, the related domain cannot be fully set up.
-
-Additionally, not all data needed for creating the hosting asset is stored in the booking item.
-It's part of the HTTP request and later stored in the hosting asset, but we also need to store it before the hosting asset can be created asynchronously.
-
-Current system behavior involves returning HTTP 201 upon booking item creation, but the automatic hosting asset creation might fail due to missing information.
-The system needs to manage the creation process in a way that ensures valid hosting assets are created and informs the user of any actions required while still returning a 201 HTTP code, not an error code.
-
-
-## Considered Options
-
-For storing the data needed for the hosting-asset creation:
-
-* STORAGE-1: Store temporary asset data in the `BookingItemEntity`, e.g. a JSON column.
-    And delete the value of that column, once the hosting assets got successfully created.
-* STORAGE-2: Create hosting assets immediately, even if invalid, but mark them as "inactive" until completed and fully validated.
-* STORAGE-3: Store the asset data in a kind of event- or job-queue, which get deleted once the hosting-asset got successfully created.
-
-For the user-notification status:
-
-* STATUS-1: Introduce a status field in the booking-items.
-* STATUS-2: Store the status in the event-/job-queue entries.
-
-### STORAGE-1: Temporary Data Storage in `BookingItemEntity`
-
-Store asset-related data (e.g., domain name) in a temporary column or JSON field in the `BookingItemEntity` until the hosting assets are successfully created.
-Once assets are created, the temporary data is deleted to avoid inconsistencies.
-
-#### Advantages
-- Easy to implement.
-
-#### Disadvantages
-- Needs either a separate map of properties in the booking-item.
-- Or, if stored as a JSON field in the booking-item-resources, these are misused. 
-- Requires additional cleanup logic to remove stale data.
-
-### STORAGE-2: Inactive Hosting Assets Until Validation
-
-Create the hosting assets immediately upon booking item creation but mark them as "inactive" until all required information (e.g., verification code) is provided and validation is complete.
-
-#### Advantages
-- Avoids temporary external data storage for the hosting-assets.
-
-#### Disadvantages
-- Validation becomes more complex as some properties need to be validated, others not.
-    And some properties even need special treatment for new entities, which then becomes vague.
-- Inactive assets have to be filtered from operational assets.
-- Potential risk of incomplete or inconsistent assets being created, which may require correction.
-- Difficult to write tests for all possible combinations of validations.
-
-### STORAGE-3: Event-Based Approach
-
-The hosting asset data required for creation us passed to the API and stored in a `BookingItemCreatedEvent`.
-If hosting asset creation cannot happen synchronously, the event is stored and processed asynchronously in batches, retrying failed asset creation as needed.
-
-#### Advantages
-- Clean-data-structure (separation of concerns).
-- Clear separation between booking item creation and hosting asset creation.
-- Only valid assets in the database.
-- Can handle complex asynchronous processes (like waiting for external verification) in a clean and structured manner.
-- Easier to manage retries and failures in asset creation without complicating the booking item structure.
-
-#### Disadvantages
-- At the Spring controller level, the whole JSON is already converted into Java objects,
-    but for storing the asset data in the even, we need JSON again.
-    This could is not just a performance-overhead but could also lead to inconsistencies.
-
-### STATUS-1: Store hosting-asset-creation-status in the `BookingItemEntity`
-
-A status field would be added to booking-items to track the creation state of related hosting assets.
-The users could check their booking-items for the status of the hosting-asset creation, error messages and further instructions.
-
-#### Advantages
-- Easy to implement.
-
-#### Disadvantages
-- Adds a field to the booking-item which is makes no sense anymore once the related hosting asset is created.
-
-
-### Status-2: Store hosting-asset-creation-status in the `BookingItemCreateEvent`
-
-A status field would be added to the booking-item-created event and get updated with the latest messages any time we try to create the hosting-asset. 
-
-#### Advantages
-- Clean-data-structure (separation of concerns)
-
-#### Disadvantages
-- Accessing the status requires querying the event queue.
-
-
-## Decision Outcome
-
-**Chosen Option: STORAGE-3 with STATUS-2 (Event-Based Approach with `BookingItemCreatedEvent`)**
-
-The event-based approach was selected as the best solution for handling automatic hosting asset creation. This option provides a clear separation between booking item creation and hosting asset creation, ensuring that no invalid or incomplete assets are created. The asynchronous nature of the event system allows for retries and external validation steps (such as user-entered verification codes) without disrupting the overall flow.
-
-By using `BookingItemCreatedEvent` to store the hosting-asset data and the status,
-we don't need to misuse other data structures for temporary data
-and therefore hava a clean separation of concerns.

 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.

 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.

-## 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 `currentSubjectOrAssumedRolesUuids()`, 
-    we could start it with the target table name and row-type,
-    then recurse down to the `currentSubjectOrAssumedRolesUuids()`.
-
-    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.

-
-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.

 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.
