Sam Tunnicliffe updated CASSANDRA-10215:
----------------------------------------
Component/s: CQL
> Reduce redundant secondary index selection lookups
> --------------------------------------------------
>
> Key: CASSANDRA-10215
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10215
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Fix For: 3.0.0 rc1
>
>
> Once an index has been identified as being the one that should be used for a
> given query, it should be included as part of the {{ReadCommand}} so that it
> can be retrieved when needed during execution. Currently we don't do this,
> meaning that the index selection process implemented in
> {{SIM::getBestIndexFor}} is run multiple times on both the coordinator and
> each replica when performing a range command.
> This is also a pre-requisite of CASSANDRA-10214
