MemCache was a name that was used and caused some confusion of what the

It has now been renamed to MemStore and is basically a write buffer that
gets flushed to disk/HDFS
when it is too big.

Not sure if there is a minimum limit but have a look at hbase-default .xml
and
you will see a bunch of settings for memStore
