Sylvain Lebresne commented on CASSANDRA-4377:
---------------------------------------------
bq. disable write access to cql3 cfs from thrift? And leave read access with
the qualification that everything will be returned as BytesType?
A variation in the same spirit could be to disable access to CQL3 table by
default but add a thrift debug mode (either per-connection through or globally
through JMX if we don't want to add a new thrift method) that would make thrift
disable every validation. That way, by default the message that CQL3 tables
should be access through CQL3 would be clear but we would have low-level
read/write for debugging.

> You can see in the above output that the stats cf is created with the column
> validator set to text, but neither of the non primary key columns defined are
> text. It should either be setting metadata for those columns or not setting a
> default validator or some combination of the two.
