> [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
