Jakub Zytka reassigned CASSANDRA-18591:
---------------------------------------
Assignee: Jakub Zytka
> assertion failure when reading after writes and column drop are executed in
> parallel
> ------------------------------------------------------------------------------------
>
> Key: CASSANDRA-18591
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18591
> Project: Cassandra
> Issue Type: Bug
> Reporter: Jakub Zytka
> Assignee: Jakub Zytka
> Priority: Normal
>
> This is another face of the problem reported in CASSANDRA-18589, but this
> problem may happen regardless of whether the dropped column is complex.
>
> When writing data in parallel with dropping a column, the subsequent reads
> may fail with AssertionError: until the affected sstable is compacted.
