> HBASE-4102 added an atomic append.  For high performance situations, it would be helpful
to be able to do appends that don't actually require a read of the existing value.  This would
be useful in building a growing set of values.  Our original use case was for implementing
a form of search in HBase where a cell would contain a list of document ids associated with
a particular keyword for search.  However it seems like it would also be useful to provide
substantial performance improvements for most Append scenarios.
> Within the client API, the simplest way to implement this would be to leverage the existing
Append api.  If the Append is marked as setReturnResults(false), use this code path.  If result
return is requested, use the existing Append implementation.
