> There are a bunch of applications that do read-modify-write operations on HBase constructs,
e.g  a counter; The counter value has to be read in from hdfs before it can be incremented.
 We have an application where the number of increments on a counter far outnumbers the number
of times the counter is used or read. For these type of applications, it will be very beneficial
to not have to read in the counter from disk before it can be incremented.
