-----------------------------------------------------------
[~twalthr] I have replied on the ML regarding to FLIP-55. Regarding to this
JIRA itself, I think we could support both of the following in the Python Table
API:
{code}
table.select(call(inc, col("id"))) \
.insert_into("sink")
table.select(inc("id")) \
.insert_into("sink")
{code}
The first example is to align with Java Table API(align with FLIP-55) and the
second example(proposed in this JIRA) could be seen as syntax sugar for Python
users as it makes use of Python specific features.

> Support to use the Python UDF directly in the Python Table API

> Key: FLINK-15974
> URL: https://issues.apache.org/jira/browse/FLINK-15974
> Project: Flink
> Issue Type: Improvement
> Components: API / Python
> Reporter: Dian Fu
> Priority: Major
> Fix For: 1.11.0
>
>
> Currently, a Python UDF has been registered before using in Python Table API,
> e.g.
> {code}
> t_env.register_function("inc", inc)
> table.select("inc(id)") \
> .insert_into("sink")
> {code}
> It would be great if we could support to use Python UDF directly in the
> Python Table API, e.g.
> {code}
> table.select(inc("id")) \
> .insert_into("sink")
> {code}
