> Key: CASSANDRA-13913
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13913
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Fix For: 3.0.x, 3.11.x
>
>
> CASSANDRA-13794 fixed the issue with fetching at most 1 extra row for SRP by
> instead fetching the per partition limit (if set) or global limit (if not).
> As noticed, however, it might be a bit too pessimistic, and double the load
> even when are only missing an extra row.
> Before 3.0.15 with that change is released, I'd like to make a small change,
> so nobody gets surprised by sudden load increases. We'd start with {{2 *
> (limit - counted)}} and if that's not enough, exponentially increase # of
> extra rows fetched until we hit {{limit}}.
