> Key: CASSANDRA-15178
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15178
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Local Write-Read Paths
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Normal
>
> The fix for CASSANDRA-15086 interacts badly with the accounting of bytes read from disk when indexed partitions are read in reverse. The skipped columns can cause the tracking of where CQL rows span index block boundaries to be incorrectly calculated, leading to rows being missing from read results.
