Also to consider is doing increments with CRDTs. See comment here

If CRDT, could do for increments only but would be sweet if other
read-modify-write ops were at least considered in design of CRDT support.
> ability to increment a counter without reading original value from storage

> 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.
