[jira] [Created] (CASSANDRA-14737) Limit the dependencies used by
UDFs/UDAs
Robert Stupp created CASSANDRA-14737:
----------------------------------------
Summary: Limit the dependencies used by UDFs/UDAs
Key: CASSANDRA-14737
URL: https://issues.apache.org/jira/browse/CASSANDRA-14737
Project: Cassandra
Issue Type: Improvement
Components: CQL
Reporter: Robert Stupp
Assignee: Robert Stupp
Fix For: 4.0
In an effort to clean up our hygiene and limit the dependencies used by UDFs/UDAs, I think we should refactor the UDF code parts and remove the dependency to the Java Driver in that area without breaking existing UDFs/UDAs.
The patch is in [this branch|https://github.com/snazy/cassandra/tree/feature/remove-udf-driver-dep-trunk]. The changes are rather trivial and provide 100% backwards compatibility for existing UDFs.
The prototype copies the necessary parts from the Java Driver into the C* source tree to {{org.apache.cassandra.cql3.functions.types}} and adopts its usages - i.e. UDF/UDA code plus {{CQLSSTableWriter}} + {{StressCQLSSTableWriter}}. The latter two classes have a reference to UDF's {{UDHelper}} and had to be changed as well.
Some functionality, like type parsing & handling, is duplicated in the code base with this prototype - once in the "current" source tree and once for UDFs. However, unifying the code paths is not trivial, since the UDF sandbox prohibits the use of internal classes (direct and likely indirect dependencies).
