ZhaoYang updated CASSANDRA-15815:
---------------------------------
Fix Version/s: 4.x
> SASI BounceIntersectionIterator should perform skipTo() using biggest token
> value
> ---------------------------------------------------------------------------------
>
> Key: CASSANDRA-15815
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15815
> Project: Cassandra
> Issue Type: Bug
> Components: Feature/SASI
> Reporter: ZhaoYang
> Priority: Normal
> Fix For: 4.x
>
>
> In {{BounceIntersectionIterator}}, it polls the {{range iterator}} which has
> the smallest current token from priority queue and uses the smallest token to
> perform skipTo() on other range iterators where their current tokens are
> equal to or greater than the smallest token... In this case, "skipTo()" works
> similarly to "next()" and no on-disk leaves will be skipped in
> {{TokenTreeIterator#performSkipTo()}}.
> I think {{BounceIntersectionIterator}} should poll the range iterator with
> biggest current token and use it to perform skipTo() to improve performance.
