Jesse Yates commented on HBASE-5723:
------------------------------------
There is a lot of work that the Lily guys have done along the lines of ensuring
consistency, but basically revolves around using a WAL for making sure the
edits get back in. Personally, I find their approach a bit heavy handed (esp
with the coprocessor framework _now_ available, though it makes sense before
CPs). They also have done a lot of work (open source!) for indexing different
data types, integration with Solr, etc. Either way, worth taking a dive into
their stuff, if only for inspiration and seeing what people who have thought a
lot about this problem have some up with.
