# Which Problems Are Solved We were seeing high query costs in a the lateral join executed in the commands_to_events procedural function in the database. The high cost resulted in incremental CPU usage as a load test continued and less req/sec handled, sarting at 836 and ending at 130 req/sec. # How the Problems Are Solved 1. Set `PARALLEL SAFE`. I noticed that this option defaults to `UNSAFE`. But it's actually safe if the function doesn't `INSERT` 2. Set the returned `ROWS 10` parameter. 3. Function is re-written in Pl/PgSQL so that we eliminate expensive joins. 4. Introduced an intermediate state that does `SELECT DISTINCT` for the aggregate so that we don't have to do an expensive lateral join. # Additional Changes Use a `COALESCE` to get the owner from the last event, instead of a `CASE` switch. # Additional Context - Function was introduced in https://github.com/zitadel/zitadel/pull/8816 - Closes https://github.com/zitadel/zitadel/issues/8352 --------- Co-authored-by: Silvan <27845747+adlerhurst@users.noreply.github.com>
