[jira] [Created] (CASSANDRA-10683) Internal pagination of CQL index queries with compact storage is suboptimal

Sam Tunnicliffe created CASSANDRA-10683:
-------------------------------------------

             Summary: Internal pagination of CQL index queries with compact storage is suboptimal
                 Key: CASSANDRA-10683
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10683
             Project: Cassandra
          Issue Type: Bug
            Reporter: Sam Tunnicliffe
            Assignee: Sam Tunnicliffe
             Fix For: 2.1.12, 2.2.4, 3.0.1


The bug in page sizing logic for {{CompositesSearcher}} described in CASSANDRA-8550 also affects {{KeysSearcher}}.
For any index with non-trivial cardinality, the page size tends to always be set suboptimally to 2, resulting in many more (smaller) slices being read the index table than necessary.
