C. Scott Andreas updated CASSANDRA-10826:
-----------------------------------------
Component/s: Documentation and Website
> frozen<> added to non-frozen UDF/UDA argument types in schema metadata
> ----------------------------------------------------------------------
>
> Key: CASSANDRA-10826
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10826
> Project: Cassandra
> Issue Type: Bug
> Components: Documentation and Website
> Reporter: Michael Penick
> Assignee: Robert Stupp
> Priority: Major
> Labels: client-impacting
>
> The function "avg_state" is created with a non-frozen tuple argument
> {{state}} and return type. It should be non-frozen because it's modified by
> the code in the body of the UDF.
> {code}
> CREATE KEYSPACE examples WITH replication = {
> 'class': 'SimpleStrategy', 'replication_factor': '3' };
> CREATE FUNCTION examples.avg_state(state tuple<int, bigint>, val int)
> CALLED ON NULL INPUT RETURNS tuple<int, bigint>
> LANGUAGE java AS
> 'if (val != null) {
> state.setInt(0, state.getInt(0) + 1);
> state.setLong(1, state.getLong(1) + val.intValue());
> }
> return state;'
> {code}
> However, the schema metadata has the both the {{state}} argument and the
> return type incorrectly defined as {{frozen<>}}:
> {code}
> cqlsh> SELECT argument_types, return_type FROM system_schema.functions WHERE
> keyspace_name = 'examples' AND function_name = 'avg_state';
> argument_types | return_type
> ---------------------------------------+----------------------------
> ['frozen<tuple<int, bigint>>', 'int'] | frozen<tuple<int, bigint>>
> {code}
