> CASSANDRA-8180 introduced {{UnfilteredRowIteratorWithLowerBound#getPartitionIndexLowerBound}} which relies on {{IndexInfo}} being present in the key-cache. But CASSANDRA-11206 will remove the presence of {{IndexInfo}} objects in-memory.
> This ticket is about to re-add that functionality if feasible.
> Currently tagged with fix-version 3.x, if it is possible to to that without changing summary or index disk structures - but maybe it's necessary to change the on-disk structure, which means we can do this in 4.x.
