Re: I need to complex Query - need big support

Hi Bodo,

I have resolved this complex query by doing small changes. What I
observed the optimizer choosing nested loop join and the storage type is in
AWS EBS type. So I decided to make random_page_cost=0 also I collected
stats + vacuumed as I said before plus now the query performing very good
and I made it down from 23 minutes into 3 minutes and 15 sec.

set local random_page_cost='0';
set local seq_page_cost='1';
set local work_mem='5GB';
set local maintenance_work_mem='15GB';
set local max_parallel_workers_per_gather='5';
