Thanks Andy. Good to know that's coming up. I started following HBASE-2038. It does seem that it's quite a bit out (I'm guess well into 2011). I think we will definitely be interested in migrating any indexes we have to the Coprocessor model. We definitely prefer to go with features supported in core. Until then though, hbase-transactional-tableindexed seems to be our best bet unless there is something else folks here suggest we do.
