--------------------------------------
Labels: client-impacting (was: )
> 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 determine the values encoding and correctly read the values from
> the query entries. Also, a batch-level setting for named values forces all
> queries to use the same encoding. Should batches force a single, homogenous
> query value encoding? (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:
> https://github.com/apache/cassandra/blob/cassandra-2.1/src/java/org/apache/cassandra/transport/messages/BatchMessage.java#L64
> Proposed solution: CASSANDRA-10247
