------------------------------------------
Summary: Names values don't work with batches
Key: CASSANDRA-10246
URL: https://issues.apache.org/jira/browse/CASSANDRA-10246
Project: Cassandra
Issue Type: Bug
Components: API
Reporter: Michael Penick
This is broken at the protocol-level and in the implementation.
At the protocol-level the {{<flags>}} component of the batch comes after the
queries. That means the protocol parser would need to read ahead (and back
track) to correctly read the values from the queries entries. Also, a
batch-level setting for named values forces all queries to use named values.
Should batches force homogenous query value types? (This is confusing)
In the implementation, values are indiscriminately read using
{{CBUtil.readValueList()}}, and the batch flags are never checked (for
{{(Flag.NAMES_FOR_VALUES}} to see if {{CBUtil.readNameAndValueList()}} should
be called instead:
