twalthr opened a new pull request #12336:
URL: https://github.com/apache/flink/pull/12336
## What is the purpose of the change
This updates catalog related operations (e.g. function DDL, SQL Client) to
the new type inference for scalar and table functions. Hive functions and
legacy planner still work with the old inference. With this we can tell a
better story about how to implement functions, because all main entrypoints
support the new inference.
## Brief change log
- Update SQL `CREATE FUNCTION` DDL
- Update SQL Client YAML file registration
- Make legacy planner more lenient
## Verifying this change
This change is already covered by existing tests.
