Andrew Purtell commented on HBASE-803:
--------------------------------------
Just a random thought but incrementors (and decrementors, etc.) could be
handled the same way row fitlers are handled: There are a standard set
implemented server side that the client can build descriptors for and send them
up in RPC invocations.
> Atomic increment operations

> Key: HBASE-803
> URL: https://issues.apache.org/jira/browse/HBASE-803
> Project: Hadoop HBase
> Issue Type: New Feature
> Components: client, ipc, regionserver
> Affects Versions: 0.2.0
> Reporter: Jonathan Gray
> Assignee: Jonathan Gray
> Priority: Minor
> Fix For: 0.2.1
>
>
> Discussion was already started in HBASE-798
> First version will contain to additional HTable methods:
> incrementColumnValue(table,row,family:column) -> Inserts a new version of the
> specified column (which must already exist) with an incremented cell value.
> incrementFamilyColumn(table,row,family: ) -> Inserts a new column under the
> specified family. This assumes the family always contains only one column.
> That column is read, incremented, deleted, and a new column is inserted with
> the incremented column name. The existing value is re-inserted unchanged to
> the new column.
> I'm going to be making even more specialized versions of these for internal
> use (taking apart byte[]'s, doing different bit/byte operations, and assorted
> munging...). So if anyone has any requests for other specialized versions,
> or more generic versions, please post them here and I'd be more than happy to
> take a stab at them.
> Next week I will likely have a go at HBASE-493
