------------------------------------
Summary: Modify "live ingest" code path to create replication
entries
Key: ACCUMULO-2579
URL: https://issues.apache.org/jira/browse/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.
