Jonathan Gray updated HBASE-803:
--------------------------------
Attachment: HBASE-803-v3-0.20.patch
HBASE-803-v3-0.19.patch
Changes HTable method to long to match HRI. Also changes logging in HRegion to
debug level, even one line per increment is noisy for info.
0.19 patch just changes Store back to HStore and RPC version from 15 to 16
(instead of 16 to 17)... What's the right thing to do here? This is actually a
unique RPC version as it's not 15, 16 or 17.

> 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
