15:18 < vines_> What are the prefix for files?
15:18 < vines_> A is a full compaction, F is a partial major compaction, I is an import.. uhhh?
15:20 < vines_> oops, F is minor, M is merging
15:20 < elserj> C was manual compact i think?
15:20 < vines_> I thought C was full
15:21 < elserj> you just said A was full
15:21 < vines_> I'm not sure
15:21 < elserj> lol
15:21 < vines_> considering I just contradicted myselkf on F
15:21 < elserj> i thought A was automatic compact and C was user-issued compact
15:21 < elserj> F was a flush, I thought
15:22 < vines_> I don't think we differentiate user interfaced or not
15:22 < vines_> C is a complete compaction - all files
15:22 < vines_> A is an incomplete major compaction
15:22 < vines_> F is a minor compaction
15:22 < vines_> M is a merging minor
15:22 < vines_> alright
15:22 < elserj> ah ok. you'd typically see the C is a user did a compact in the shell
15:22 < elserj> unless you set your ratio to something dumb?
15:23 < elserj> that's probably what i was thinking of
15:26 -!- ericnewton_ [~ecnewt2-l@pool-96-244-143-107.bltmmd.fios.verizon.net] has quit [Remote host closed the connection]
15:33 < vines_> perhaps
15:40 -!- jmhsieh [~jmhsieh@65.50.196.130] has quit [Ping timeout: 264 seconds]
15:43 < madrob> A is all.
15:43 < madrob> C is partial
15:43 < madrob> F is flush
15:49 < busbey> could someone file a Jira to document this?
15:49 < busbey> nevermind, I'll do it. ;)

I'm not sure where the correct place for this is. I'm guessing somewhere in javadocs. Maybe in an advanced section of the administration manual?
