Subject [jira] [Created] (ACCUMULO-2579) Modify "live ingest" code path to create replication entries
Date Fri, 28 Mar 2014 02:31:16 GMT
Josh Elser created ACCUMULO-2579:

             Summary: Modify "live ingest" code path to create replication entries
                 Key: ACCUMULO-2579
             Project: Accumulo
          Issue Type: Sub-task
            Reporter: Josh Elser
             Fix For: 1.7.0

When new writes come in to a server, we want to track the updates to the WAL, and ensure that
we create entries to track that we need to replicate that data.

Supporting replication over portions of a WAL is desirable to reduce replication latency,
but this may decrease the total ingest throughput.
Despite not wanting to persist a replication record for every update, but we might need to
so we can ensure that we don't miss data that needs replication. Need to observe how things
like the tserver processes BatchWriter updates -- I believe the problem is analogous.
