+# 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.
+
+
+## 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 10-25 minutes**.
+
+We could not find a pattern, why the import mostly took about 25 minutes, but sometimes took *just* 10 minutes. 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:
+
+```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:
+
+```

+    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/

+## Summary
+
+That the import runtime is down to about 12min is repeatable, where originally, the import took about 25mins in most cases and just rarely - and for unknown reasons - just 10min.
+
+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 neccessary, reduced the total runtime of the import to about the half.
