ryan rawson commented on HBASE-3434:
------------------------------------
can we layer this on top of the existing infrastructure, instead of
making fundamental changes to KeyValue and HFile? Or if we must make
changes, let's do it in very minimal ways, eg: add 1 or 2 more types
to KV.

> Key: HBASE-3434
> URL: https://issues.apache.org/jira/browse/HBASE-3434
> Project: HBase
> Issue Type: Improvement
> Components: client, regionserver

> 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.
