Hello,
I am having performance issues with one of the query.
The query is taking 39 min to fetch 3.5 mil records.
I want to reduce that time to 15 mins.
could you please suggest something to its performance?
server configuration:
CPUs = 4
memory = 16 GM
shared_buffers = 3 GB
work_mem = 100MB
effective_cache_size = 12 GB
we are doing the vacuum/analyze regularly on the database.
attached is the query with its explain plan.
Thanks,
Samir Magar
