Erik Holstad commented on HBASE-1249:
-------------------------------------
Some more thoughts for puts into memCache.
I think that when writing a delete to memCache and timestamp is specified we
should just overwrite the value in there and not save both.
When we get a more complicated deletes such as row, family etc, I propose that
we after that insert walk down the tailTree of that node and
delete all it's children. This will result in less flushing of memCache and
make things easier when reading.
