------------------------------------
Assignee: Timo Walther
> 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
> Assignee: Timo Walther
> Priority: Major
>
> 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].
