Jonathan Gray updated HBASE-803:
--------------------------------
Description:
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
