             Summary: Transmit only latest snapshot of Invalid list to client 
and Tx co-processor
                 Key: TEPHRA-193
                 URL: https://issues.apache.org/jira/browse/TEPHRA-193
             Project: Tephra
          Issue Type: Sub-task
          Components: core
            Reporter: Poorna Chandra
            Assignee: Poorna Chandra

Invalid list can grow over time, and transferring it over to region server for 
every transaction can lead to sub-optimal performance. Since transaction 
co-processors already have access to transaction snapshots (with a few mins 
delay), it would be efficient to only transmit the delta invalid list newer 
than the snapshot the co-processors have access to.
