Subsequent work found that increment performance had been restored as a side-effect of HBASE-12751. Enabling this 'feature', gets you a worst state than not enabling it; if increments and mutation types like put or delete cross on the same Cell coordinates, the results will be indeteminate (increments are coherent for increment operations only). I've tried to message this when talking about the increment regression. For example, see the release note here [1]. HBASE-15224, the patch I just applied to branch-1.2, removes the 'fast path' internally. If a user has set the config to turn it on for 1.2.0, they will have increments with the above mentioned compromise. The user should be aware since they found the option to enable the 'fast path' in the release notes that talk of the fast paths' limitation. When they upgrade to 1.2.1 with HBASE-15224 in place, the configuration will be just ignored. Maybe a note in notes that accompany the release but not a reason to sink the RC IMO.
