Jean-Daniel Cryans updated HBASE-3009:
--------------------------------------

    Attachment: HBASE-3009.patch

Patch that adds the desired behavior. It requires that the family is configured to only keep one version and that the Put is done only one cell. It's kinda hacky.

> We had an internal need for a method to update a single cell thousands of times per second without having a "versions explosion" problem, and found that the code can be somewhat easily modified for that by reusing Store.updateColumnValue and making it accept byte[]. I'm putting the patch here in case someone else finds it useful, and maybe it can eventually make its way into the source.
