------------------------------------------

> CDC and VIEW writeType missing from spec for write_timeout / write_failure
> --------------------------------------------------------------------------
>
> Key: CASSANDRA-13697
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13697
> Project: Cassandra
> Issue Type: Improvement
> Components: Documentation and Website
> Reporter: Andy Tolbert
> Assignee: Vinay Chella
> Priority: Minor
> Labels: lhf
>
> 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.
