URL: https://github.com/apache/datafusion-java/issues/36
### Is your feature request related to a problem or challenge?
DataFusion 53.1 supports Avro via `SessionContext::read_avro` /
`register_avro`, but the Java binding doesn't expose it. Parquet (#18)
and CSV (#21) are covered; Avro is the remaining commonly requested
columnar/row format for analytics workloads.
### Describe the solution you'd like
Mirror the existing reader pattern:
- Add an `AvroReadOptions` value class (file extension, schema).
- Add `proto/avro_read_options.proto` and pass options through the
proto-over-JNI convention (#29).
- Expose `SessionContext.registerAvro(name, path[, options])` and
`readAvro(path[, options])`.
- Cover with tests against a small fixture Avro file.
### Describe alternatives you've considered
`CREATE EXTERNAL TABLE … STORED AS AVRO` via SQL works but bypasses
the typed builder.
### Additional context
Avro support in DataFusion lives behind the `avro` Cargo feature. The
native crate currently relies on DataFusion's default features
(restored in e79dc7e); enabling `avro` will pull in the `apache-avro`
crate and grow the native binary. Worth confirming the size impact is
acceptable before merging.
