> Key: CASSANDRA-14873
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14873
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Local Write-Read Paths
> Reporter: Aleksey Yeschenko
> Assignee: Aleksey Yeschenko
> Priority: Urgent
> Fix For: 3.0.18, 3.11.4
>
>
> If a partition has a static row and is large enough to be indexed, then
> {{firstName}} of the first index block will be set to a static clustering.
> When deserializing the column index we then incorrectly deserialize the
> {{firstName}} as a regular, non-{{STATIC}} {{Clustering}} - a singleton array
> with an empty {{ByteBuffer}} to be exact. Depending on the clustering
> comparator, this can trip up binary search over {{IndexInfo}} list and cause
> an incorrect resultset to be returned.
