> Key: CASSANDRA-10560
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10560
> Project: Cassandra
> Issue Type: Bug
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Fix For: 3.0.0
>
>
> For single partition reads, we currently perform an unnecessary call to
> SecondaryIndexManager to lookup the most selective index based on the
> command's RowFilter. This is redundant as if any applicable indexes are
> present, the query would be performed using a range command (there was some
> code introduced into {{CassandraIndexSearcher}} by CASSANDRA-8099 in
> preparation for supporting indexes on single partition reads, but it is as
> yet unused). Given that, we should make sure we don't perform that lookup for
> now.
