URL: https://github.com/apache/hudi/pull/6135
## What is the purpose of the pull request
- Adds support for a ProtoKafkaSource based on RFC 57
## Brief change log
- Adds `PROTO` to `Source.SourceType` enum
- Handles `PROTO` type in `SourceFormatAdapter` by converting to Avro from
proto Message objects. Conversion to Row goes Proto -> Avro -> Row currently
- Added `ProtoClassBasedSchemaProvider` to generate schemas for a proto
class that is currently on the classpath
- Added `ProtoKafkaSource` which parses byte[] into a class that is on the
path
- Added `ProtoConversionUtil` which exposes methods for creating schemas
and translating from Proto messages to Avro GenericRecords
## Verify this pull request
This change added tests and can be verified as follows:
- Added `TestProtoKafkaSource` to validate the flow from Kafka to Hudi
- Added `TestProtoClassBasedSchemaProvider` to validate schemas are
properly generated
- Added `TestProtoConversionUtil` to validate the conversion from Proto to
Avro is working as expected for all proto types
