---------------------------------------
Summary: Upgrade protobuf-java from 3.x to 4.32.1 with
compatibility patch for parquet-protobuf
Key: FLINK-38547
URL: https://issues.apache.org/jira/browse/FLINK-38547
Project: Flink
Issue Type: Improvement
Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
Affects Versions: 2.1.0
Reporter: Khaled Hammouda
Flink currently uses protobuf-java 3.x, causing incompatibility issues with
applications trying to use protobuf 4.x.
In particular, `flink-formats/flink-protobuf` still uses a protobuf 3.x API
that were removed (Descriptors.FileDescriptor.Syntax enum used for
proto2/proto3 syntax detection).
Also, the `parquet-protobuf` dependency (parquet-java 1.15.2) still uses the
same API, and thus requires a local patch until the same protobuf version
upgrade is completed upstream
([https://github.com/apache/parquet-java/issues/3175).]
I'll can submit a PR that implements this upgrade.
