Andy Tolbert created CASSANDRA-13697:
----------------------------------------
Summary: 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
Reporter: Andy Tolbert
Priority: Minor
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.
