> 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.
