Jeff Jirsa commented on CASSANDRA-13384:
----------------------------------------

I intend to drop it on the merge to master - would only exist for 3.0 and 3.11

>            Priority: Minor
>             Fix For: 3.0.x, 3.11.x

> In 2.1, we wrote caching options as a JSONified map, but we tolerated raw strings ["ALL",
"KEYS_ONLY", "ROWS_ONLY", and "NONE"|https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/cache/CachingOptions.java#L42].
> If a 2.1 node with any of these strings is upgraded to 3.0, the legacy schema migration
will fail.
