Optimizing postgresql table for more than 100K inserts per second

Optimizing postgresql table for more than 100K inserts per second

  • Create UNLOGGED table. This reduces the amount of data written to persistent storage by up to 2x.
  • Set WITH (autovacuum_enabled=false) on the table. This saves CPU time and IO bandwidth on useless vacuuming of the table (since we never DELETE or UPDATE the table).
  • Insert rows with COPY FROM STDIN. This is the fastest possible approach to insert rows into table.
  • Minimize the number of indexes in the table, since they slow down inserts. Usually an index on time timestamp with time zone is enough.
  • Add synchronous_commit = off to postgresql.conf.
  • Use table inheritance for fast removal of old data:

List of some useful Stat Queries for PSQL
--- PSQL queries which also duplicated from https://github.com/anvk/AwesomePSQLList/blob/master/README.md
--- some of them taken from https://www.slideshare.net/alexeylesovsky/deep-dive-into-postgresql-statistics-54594192
-- I'm not an expert in PSQL. Just a developer who is trying to accumulate useful stat queries which could potentially explain problems in your Postgres DB.
