1.Is hbase.client.keyvalue.maxsize  is max size of row or key only ? Is
there any limit on key size only ?
2.Access pattern is mostly on key based only- Is memstores and regions on a
regionserver are per table basis? Is it if I have multiple tables it will
have multiple memstores instead of few if it would have been one large
table ?
