Subject [jira] [Commented] (HBASE-17277) Allow alternate BufferedMutator implementation
Date Thu, 08 Dec 2016 16:50:58 GMT

stack commented on HBASE-17277:
-------------------------------

bq. This means normally the alternate BM impl has to extend the existing one right? 

I should change it from private. Will see what implementators want to do ([~jrottinghuis]
and [~vrushalic]) first.

bq. Can we allow some sort of a callback impl or when the BM tries and fails to flush the
mutations in buffered? The impl of such a callback can work with the spooling? We would allow
some way to clear off the buffer also then. Just random thoughts...

Yeah. This sounds like the way to go. AP will change. AP is too complicated. Exposing a few
points of transition seems way to go.

> Allow being able to supply alternate BufferedMutator implementation. For example, the
parent issue would like to spool writes to the filesystem if hbase is down.
