---------------------------------------------
Summary: Avoid unnecessary deserialization of terminal arguments
when executing CQL functions
Key: CASSANDRA-18566
URL: https://issues.apache.org/jira/browse/CASSANDRA-18566
Project: Cassandra
Issue Type: Improvement
Components: CQL/Semantics
Reporter: Andres de la Peña
Assignee: Andres de la Peña
CQL functions unnecessarily deserialize their terminal arguments on every call.
For example, the function call in {{SELECT mask_inner(column, 1, 0) FROM t}}
deserializes {{1}} and {{2}} for each returned row. As another example, the
selector in {{SELECT column * 2 FROM t}} also deserializes {{2}} for each
returned row.
The goal of this ticket is to improve the function execution code to avoid
those deserializations.
