> 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.
