When acknowledgement  is used in a table strategy the main river source_operation for each item is updated to 'ack'
To prevent connection locks in this scenario we are using the same connection. (writeConnection)
Support for Oracle XMLDB XMLType column with proper stream closing.
Support for elastic search 0.21.Beta1-Snapshot including partial document updates via Bulk API
- minor changes to make jdbc-river work on 0.21 branch instead of 0.90
- Changed the acknowledgement of bulk request in inserts instead of updates. ( with no update on river source table to avoid deadlocks)
