----------------------------------------
Summary: Store temporary functions as CatalogFunctions in
FunctionCatalog
Key: FLINK-15860
URL: https://issues.apache.org/jira/browse/FLINK-15860
Project: Flink
Issue Type: Improvement
Components: Table SQL / API
Reporter: Dawid Wysakowicz
Fix For: 1.11.0
We should change the {{FunctionCatalog}} so that it stores temporary functions
as {{CatalogFunction}}s instead of instances of {{FunctionDefinition}} the same
way we store {{CatalogTable}}s for temporary tables.
For functions that were registered with their instance we should create a
{{CatalogFunction}} wrapper similar to {{ConnectorCatalogTable}}.
