Hi Team, One of the queries, which retrieves a single record from a table with 16 hash partitions, is taking more than 10 seconds to execute. In contrast, when we run the same query manually, it completes within milliseconds. This issue is causing exhaustion of the application pools. Do we have any bugs in postgrs16 hash partitions? Please find the attached log, table, and execution plan.
size of the each partitions : 300GB Index Size : 12GB Postgres Version : 16.x Shared Buffers : 75 GB Effective_cache : 175 GB Work _mem : 4MB Max_connections : 3000 OS : Ubuntu 22.04 Ram : 384 GB CPU : 64 Please let us know if you need any further information or if there are additional details required. Regards, Ram.
