             Summary: [BRAINSTORMING] Support read-your-own-writes semantics without sending updates to server
                 Key: PHOENIX-2092
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2092
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor


Our current transaction integration sends uncommitted data to the HBase server when a client attempts to read on a connection with uncommitted data. Instead, we could (in theory) keep the data on the client and treat these local edits as a kind of separate region which would get merged into the results of any queries. Unclear how many cases would be handled, though:
- partially aggregated results would need to be adjusted (i.e. subtract the sum from an overridden value and add the sum from the new value)
- secondary index usage - the client would need to know the rows to delete and the rows to add to the index table
- deleted rows

Parking this here for now as food for thought.
