Easily copy and paste the code under the badges into your Markdown files.
- The badges do not fully replace the license informations for your projects, they are only emblems for the README, that the user can see the License at first glance.

- 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 neverDELETE
orUPDATE
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

time timestamp with time zone
is enough. - Add
synchronous_commit = off
topostgresql.conf
. - Use table inheritance for fast removal of old data:
