Description

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.
