Обсуждение: group commit
Hi,
i just wanted to know if group commit (as described in https://wiki.postgresql.org/wiki/Group_commit ) was committed.
And if parallel replication is going to be introduced.
Mysql 5.7 going to have intra-database parallel slave based on group commit on master.

I guess that depends on whether this comment in the 9.2 release notes covers the same material described in the linked wiki page (I would presume it does). http://www.postgresql.org/docs/9.2/interactive/release-9-2.html Section: E.9.3.1.1.

Though based upon your question regarding parallel replication I am thinking that maybe your concept of "group commit" and the one that was implemented are quite different...
