------------------------------------------
> I didn't see any conflict. It seems user can still use AvroReadSupport to set

How can I use the {{AvroReadSupport}}? There is no method to pass configuration
in {{AvroParquetReaders}} nor in {{AvroParquetRecordFormat}}
> It make sense to mark AvroParquetReaders as Experimental. The class

{{Experimental}} is used to mark features that are in early stage of
development and we are not confident about its readiness for production use.
After playing around with AvroParquetReaders I find it not ready for production
use. I don't see any relation with {{StreamFormat}} here. E.g. not all
connectors need to be PublicEvolving from day one, just because the Source API
is PublicEvolving.

> Project: Flink
> Issue Type: Improvement
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
> Reporter: Jing Ge
> Assignee: Dawid Wysakowicz
> Priority: Blocker

> Fix For: 1.15.0

> The following scenarios are worthwhile to test
> * Start a simple job with None/At-least-once/exactly-once delivery guarantee
> read Avro Generic/sSpecific/Reflect records and write them to an arbitrary
> sink.
> * Start the above job with bounded/unbounded data.
> * Start the above job with streaming/batch execution mode.
>
> This format works with FileSource[2] and can only be used with DataStream.
> Normal parquet files can be used as test files. Schema introduced at [1]
> could be used.
