Hello,
I have implemented per query network stat collection for FDW. It is done
in a similar way to how buffer and WAL stats are collected and it can be
seen with a new NETWORK option for explain command:
explain (analyze, network) insert into itrtest values (2, 'blah');
QUERY PLAN
-----------------------------------------------------------------------------------------------
Insert on itrtest (cost=0.00..0.01 rows=0 width=0) (actual
time=0.544..0.544 rows=0 loops=1)
Network: FDW bytes sent=197 received=72, wait_time=0.689
-> Result (cost=0.00..0.01 rows=1 width=36) (actual
time=0.003..0.003 rows=1 loops=1)
Planning Time: 0.025 ms
Execution Time: 0.701 ms
(5 rows)
I am yet to add corresponding columns to pg_stat_statements, write tests
and documentation, but before I go ahead with that, I would like to know
what the community thinks about the patch.
Regards,
Ilya Gladyshev
