aramkumar06 / Optimizing postgresql

Last active January 25, 2020 16:07 — forked from valyala/README.md

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:
