[jira] [Commented] (CASSANDRA-9037) Terminal UDFs evaluated at
prepare time throw protocol version error
[ https://issues.apache.org/jira/browse/CASSANDRA-9037?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14379776#comment-14379776 ]
Sam Tunnicliffe commented on CASSANDRA-9037:
--------------------------------------------
We should use the version from {{ProtocolVersion.NEWEST_SUPPORTED}} to ensure we don't get ahead of the included driver. Unfortunately, C* uses a simple int to represent this version (in {{QueryOptions}} for instance) but the driver's {{ProtocolVersion}} doesn't expose the version number in this way so I've opened [JAVA-700|https://datastax-oss.atlassian.net/browse/JAVA-700] to do so.
[This branch|https://github.com/beobal/cassandra/tree/9037] includes a unit test & a SNAPSHOT driver jar build from [the JAVA-700 pull request|https://github.com/datastax/java-driver/pull/308]

> When a pure function with only terminal arguments (or with no arguments) is used in a where clause, it's executed at prepare time and {{Server.CURRENT_VERSION}} passed as the protocol version for serialization purposes. For native functions, this isn't a problem, but UDFs use classes in the bundled java-driver-core jar for (de)serialization of args and return values. When {{Server.CURRENT_VERSION}} is greater than the highest version supported by the bundled java driver the execution fails with the following exception:
