------------------------------------
Summary: 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
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.
