Hi admins,
Is there a limit to number of tables that a cluster can support?
https://www.postgresql.org/docs/13/limits.htmlAt the moment, one of my clusters has about 250k user tables (plus 150k toast tables) across a hundred schemas within a single database.
My application team wants to double the number of schemas (and with it the tables)
I am looking for both pros and cons of doing this and what tuning can help this cluster perform acceptably.
My questions are
1. Is there a limit to number of tables a cluster can support effectively?
2. My guess is autovacuum would have to be tuned. Current gucs for this are
max_autovacuum_workers = 6
maintenance_work_mem = 1GB
autovacuum_vacuum_scale_factor = 0.2
autovacuum_vacuum_cost_delay = 20ms
Are there any potential problems that I need to think about ?
My machine specs are as below.
RAM 256GB
32-core CPU
7TB SSD
thanks
karthik
