tsreaper opened a new pull request #17565:
URL: https://github.com/apache/flink/pull/17565
## What is the purpose of the change
Currently `AvroToRowDataConverters#createRowConverter` converts avro records
to Flink row data directly without any projection. However users of this
method, such as `AvroFileSystemFormatFactory.RowDataAvroInputFormat`, need to
implement their own projection logic to filter out the columns they needed.
This PR hides the logic of implementation in
`AvroToRowDataConverters#createRowConverter` both for optimization (users do
not need to copy the row for this) and for the ease of coding.
## Brief change log
- Implement row projection in `AvroToRowDataConverters#createRowConverter`.
## Verifying this change
