------------------------------------------------------------------------
Maybe we can add a new configuration option (something like
"enable_big_collection_values") which is default to false in 2.1 and 2.2 so
nothing changes unless some wants it, and is default to true on >= 3.0 (or
doesn't exist at all), with a proper comment (in 2.1/2.2) which inform users
that enabling that option breakes compatibility with protocols v1 and v2.
Can this be good enough ?

> List and Map values incorrectly limited to 64k size

> Key: CASSANDRA-10374
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10374
> Project: Cassandra
> Issue Type: Bug
> Reporter: Tyler Hobbs
> Assignee: Benjamin Lerer
> Priority: Minor
> Fix For: 3.0.1, 3.1, 2.1.x, 2.2.x
>
>
> With the v3 native protocol, we switched from encoding collection element
> sizes with shorts to ints. However, in {{Lists.java}} and {{Maps.java}}, we
> still validate that list and map values are smaller than
> {{MAX_UNSIGNED_SHORT}}.
> Map keys and set elements are stored in the cell name, so they're implicitly
> limited to the cell name size limit of 64k. However, for non-frozen
> collections, this limitation should not apply, so we probably don't want to
> perform this check here for those either.
> The fix should include tests where we exceed the 64k limit for frozen and
> non-frozen collections. In the case of non-frozen lists and maps, we should
> verify that the 64k cell-name size limit is enforced in a friendly way.
