[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Postgresql Experts,

We have a basic requirement where we need to implement the parallel index scan instead of parallel seq scan at table level. Please suggest the best way to do this.

Postgresql DB Version : 12.6

Table size : 2-5 GB

OS : Centos-7

RAM : 96 GB
CPU : 32

shared_buffer=20GB
Effective_cache_size=60GB

Max_worker_process = 32
Max_parallel_worker=32
Max_parallel_worker_per_gather=8

Please let me know if any further details required .

Thanks & Regards,

Singh
