echauchot opened a new pull request #15156:
URL: https://github.com/apache/flink/pull/15156
## What is the purpose of the change
*(For example: This pull request makes task deployment go through the blob
server, rather than through RPC. That way we avoid re-transferring them on each
deployment (during recovery).)*
Implement ParquetAvroInputFormat
## Verifying this change
This change added tests and can be verified as follows:
new ParquetAvroInputFormatTest test both simple record and projected fields
with simple record but sets parquet.avro.write-old-list-structure to true
because AvroRowSerializationSchema does not work with
parquet.avro.write-old-list-structure set to false
## Does this pull request potentially affect one of the following parts:
- Dependencies (does it add or upgrade a dependency): no
- The public API, i.e., is any changed class annotated with
`@Public(Evolving)`: yes adds new API (new input format)
- The serializers: not really, just make
AvroRowSerializationSchema#convertRowToAvroRecord public
- The runtime per-record code paths (performance sensitive): yes as
ParquetInputFormat#convert is implemented
- Anything that affects deployment or recovery: JobManager (and its
components), Checkpointing, Kubernetes/Yarn/Mesos, ZooKeeper: no
- The S3 file system connector: no
## Documentation
- Does this pull request introduce a new feature? yes
- If yes, how is the feature documented? javadoc with code example
