Subject Re: Status of Huawei's 2' Indexing?
Date Thu, 12 Mar 2015 22:58:48 GMT
I saw that it was added to their project. I’m really not keen on bringing
in all the RDBMS apparatus on top of hbase, so I decided to follow other
avenues first (like trying to patch 0.98, for better or worse.)

That Phoenix article seems like a good breakdown of the various indexing
architectures.

HBASE-9203 (the ticket that deals with 2’ indexes) is pretty civilized (as
are most of them, it seems) so I didn’t know there were these differences
of opinion. Did I miss the mailing list thread where the architectural
differences were discussed?
