Kirk True commented on CASSANDRA-13697:
---------------------------------------

Also appears to be missing {{CAS}} enum as well.

> In cassandra 3.0 a new {{WriteType}} {{VIEW}} was added which appears to be used when
raising a {{WriteTimeoutException}} when the local view lock for a key cannot be acquired
within timeout.
> In cassandra 3.8 {{CDC}} {{WriteType}} was added for when {{cdc_total_space_in_mb}} is
exceeded when doing a write to data tracked by cdc.
> The [v4 spec|https://github.com/apache/cassandra/blob/cassandra-3.11.0/doc/native_protocol_v4.spec#L1051-L1066]
currently doesn't cover these two write types.   While the protocol allows for a free form
string for write type, it would be nice to document that types are available since some drivers
(java, cpp, python) attempt to deserialize write type into an enum and may not handle it well.
