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
