Jonathan Ellis commented on CASSANDRA-3057:
-------------------------------------------
(technically, the value becomes a row key, which happens to have the same size
limit as column names.)
> secondary index on a column that has a value of size > 64k will fail on flush
> -----------------------------------------------------------------------------

> Key: CASSANDRA-3057
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3057
> Project: Cassandra
> Issue Type: Bug
> Reporter: Jackson Chung
> Assignee: Pavel Yaskevich
> Priority: Minor
>
> exception seen on flush when an indexed column contain size > 64k:
> granted that having a value > 64k possibly mean something that shouldn't be
> indexed as it most likely would have a high cardinality, but i think there
> would still be some valid use case for it.
> test case:
> simply run the stress test with
> -n 1 -u 0 -c 2 -y Standard -o INSERT -S 65536 -x KEYS
> then call a flush
> exception:
