Branimir Lambov commented on CASSANDRA-7237:
--------------------------------------------
The batch log does not currently use the local partitioner and thus it does not
order tokens by time. Implementing this involves change of partitioner.
Retargeting for 3.0.
> Optimize batchlog manager to avoid full scans

> URL: https://issues.apache.org/jira/browse/CASSANDRA-7237
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Aleksey Yeschenko
> Assignee: Branimir Lambov
> Priority: Minor
> Fix For: 3.0
>
>
> Now that we use time-UUIDs for batchlog ids, and given that w/ local strategy
> the partitions are ordered in time-order here, we can optimize the scanning
> by limiting the range to replay taking the last replayed batch's id as the
> beginning of the range, and uuid(now+timeout) as its end.
