Description

[14:53:10] <jdcryans> I'd say 80% of the time you should just let it happen naturally
[14:53:26] <jdcryans> the main thing is deciding how often you want to major compact
[14:53:38] <jdcryans> some people disable it completely because they don't update/delete
[14:53:58] <jdcryans> others may decide to do it weekly because they don't update/delete that often
[14:54:18] <jdcryans> and then there's the aggressive default of doing it every 24h
[14:55:39] <jdcryans> and it looks like the default is now 1 week un trunk

[14:58:35] <jdcryans> automatic major* compactions
