> Optimize batchlog manager to avoid full scans
> ---------------------------------------------
>
> Key: CASSANDRA-7237
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7237
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Aleksey Yeschenko
> Assignee: Branimir Lambov
> Priority: Minor
> Fix For: 3.0.0 rc1
>
>
> 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.
