Hi all,
App team using connection pooling and opening 500 sessions which seems to
me stay ,
In this case pgbouncer session pooling or transaction pooling which is
better?
Max_connections in db: 1000
Pool_mode=session
Max connections in pgbouncer: 3000
Default_pool_size=500
Reserve_pool_size=100
Min_pool_size=20

Transaction pooling.

Too big. Set default_pool_size = min_pool_size = 20, and set reserve_pool_size = 0.
If that turns out to be too small, increase slightly.
