Subject AW: Amazon RDS for PostgreSQL Support
Date Wed, 29 Nov 2017 21:46:54 GMT

since nobody responded, we started to experiment.

AWS RDS Postgres 9.6.3
db.m4.xlarge (4 cores, 16 GB RAM)
provisioned iops 4000

Indexing Performance for most jobs is pretty good, except a for a bigger sharepoint crawl
(~200.000 docs).

We are seeing a lot of long running queries for the tables carrydown here.


(due to this discussion we left autovac on:

CPU Usage of the Database is between 15% and 35%

Are we hitting bad auto optimiziations of the newer postgresql version?

Many thanks in advance,
