> A recent conversation on #Accumulo pointed out a need for better documentation on how we store state in RFile names

> 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
> 15:33 < vines_> perhaps
> 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?
