Jonathan Ellis commented on CASSANDRA-3057:
-------------------------------------------
We're already looping through ColumnDefinitions for getValueValidator, let's
extract a getColumnDefinition from that so we only do the search once.
> secondary index on a column that has a value of size > 64k will fail on flush

>
> 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:
