Обсуждение: direct_cp 1.0.0 is released!
Hi all,
Last week, we released direct_cp that is archiving WAL command without waste file caches.
In general, archiving WAL copy cause less performance, because it creates a lot of not re-accessed OS file caches. To use direct_cp, OS file caches are more efficiently used in PostgreSQL. It can easy to use that replace cp command with direct_cp at archive command in postgresql.conf.
* Install package is under following.
* Performance test in archive mode is under following.
direct_cp can realize better performance than normal cp command.
* Online manual is under following.
This software is BSD License.
Please apply it to your postgres with archiving mode.
Regards,
