xueyu updated FLINK-10689:
--------------------------
External issue URL: https://github.com/apache/flink/pull/7059
Labels: pull-request-available (was: )
The UserDefinedFunction, ScalarFunction, TableFunction, FunctionContext,
AggregateFunction and DistinctAggregateFunction is ported in the PR #7059,
exept FunctionService, TemporalTableFunction and subpackage in
org.apache.flink.table.functions.aggfunctions.
These two could be ported then the following.
FunctionService looks need to port other several descriptors alongside and
TemporalTableFunction looks need some more work than others. I am not sure
whether the way in the PR is right, so just submitted as first stage. If these
ports is right after review the remaing two files could be ported then.
For TemporalTableFunction, do we also need to use scala implicit to process
table dependency such as Table and Expression? Thanks~ [~twalthr]
