----------------------------------------

             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}}.
