[jira] [Created] (FLINK-22878) Allow placeholder options in format factories

Timo Walther created FLINK-22878:
------------------------------------

             Summary: Allow placeholder options in format factories
                 Key: FLINK-22878
                 URL: https://issues.apache.org/jira/browse/FLINK-22878
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Timo Walther


The current factory design does not allow placeholder options in {{EncodingFormatFactory}} or {{DecodingFormatFactory}}.

The past has shown that placeholder options are used at a couple of locations.
See FLINK-22475 or {{KafkaOptions#PROPERTIES_PREFIX}}.

We should think about adding an additional functionality to {{ReadableConfig}} or a special {{ConfigOption}} type to finally solve this problem. This could also be useful for FLIP-129. And would solve the [current shortcomings for Confluent Avro registry|https://github.com/apache/flink/pull/15808#discussion_r645494282].
