Subject [jira] Commented: (HBASE-1845) Discussion issue for multi calls, MultiDelete, MultiGet and MultiPut
Date Mon, 09 Nov 2009 16:47:35 GMT

Erik Holstad commented on HBASE-1845:
-------------------------------------

@Andrew
I haven't worked on this for a little while, but they way I was thinking it is that the failed
inserts gets returned separately from the successful once and that only the failed are retried.
If the code that you have looked at doesn't do that, it is wrong. 

About the write buffer I'm not sure how we want to do, since I think that we are gong to be
able to mix calls, get, puts and deletes in a single multi call, so we have to decide if this
is something that makes sense and in that case maybe not use the write buffer. But like I
said earlier, havn't looked at the code recently, so don't exactly remember.
