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

             Summary: GetTable from Flink catalog should be judged whether it 
is a sink table
                 Key: FLINK-30884
                 URL: https://issues.apache.org/jira/browse/FLINK-30884
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API, Table SQL / Planner
    Affects Versions: 1.16.1
            Reporter: yuanfenghu


I want to say that when I use a third-party persistent catalog to manage the 
metadata of my persistent table,

I may want to judge the options of the table I need to generate by whether it 
is a sink table

For example when using kafka connector

When I use kafka as source table,

The following parameters are required:

offset, properties.group.id, etc.

When I use kafka as the sink representation, I will pass in some parameters 
only about the sink table, for example:

sink.delivery-guarantee

sink.partitioner

So why can't we add a switch to tell the catalog this information, which is 
very useful in platform development! !
