feat: implement Protobuf index varints handling
- Add proper varint encoding/decoding functions in envelope.go - Implement CreateConfluentEnvelope with varint encoding for Protobuf indexes - Add ParseConfluentProtobufEnvelopeWithIndexCount for reliable parsing when index count is known - Add ParseConfluentProtobufEnvelope with conservative approach (assumes no indexes by default) - Remove duplicate functions from protobuf_decoder.go to avoid conflicts - Create comprehensive test suite in envelope_varint_test.go covering: - Basic varint encode/decode functionality - Confluent envelope creation and parsing with various index scenarios - Round-trip testing for Protobuf envelopes - Edge cases and validation - Document limitations of heuristic-based parsing and provide explicit index count alternative Tests: All varint and envelope tests pass, proper handling of Protobuf message indexes |

persist kafka offset
Phase E2: Integrate Protobuf descriptor parser with decoder - Update NewProtobufDecoder to use ProtobufDescriptorParser - Add findFirstMessageName helper for automatic message detection - Fix ParseBinaryDescriptor to return schema even on resolution failure - Add comprehensive tests for protobuf decoder integration - Improve error handling and caching behavior This enables proper binary descriptor parsing in the protobuf decoder, completing the integration between descriptor parsing and decoding. Phase E3: Complete Protobuf message descriptor resolution - Implement full protobuf descriptor resolution using protoreflect API - Add buildFileDescriptor and findMessageInFileDescriptor methods - Support nested message resolution with findNestedMessageDescriptor - Add proper mutex protection for thread-safe cache access - Update all test data to use proper field cardinality labels - Update test expectations to handle successful descriptor resolution - Enable full protobuf decoder creation from binary descriptors Phase E (Protobuf Support) is now complete: ✅ E1: Binary descriptor parsing ✅ E2: Decoder integration ✅ E3: Full message descriptor resolution Protobuf messages can now be fully parsed and decoded Phase F: Implement Kafka record batch compression support - Add comprehensive compression module supporting gzip/snappy/lz4/zstd - Implement RecordBatchParser with full compression and CRC validation - Support compression codec extraction from record batch attributes - Add compression/decompression for all major Kafka codecs - Integrate compression support into Produce and Fetch handlers - Add extensive unit tests for all compression codecs - Support round-trip compression/decompression with proper error handling - Add performance benchmarks for compression operations Key features: ✅ Gzip compression (ratio: 0.02) ✅ Snappy compression (ratio: 0.06, fastest) ✅ LZ4 compression (ratio: 0.02) ✅ Zstd compression (ratio: 0.01, best compression) ✅ CRC32 validation for record batch integrity ✅ Proper Kafka record batch format v2 parsing ✅ Backward compatibility with uncompressed records Phase F (Compression Handling) is now complete. Phase G: Implement advanced schema compatibility checking and migration - Add comprehensive SchemaEvolutionChecker with full compatibility rules - Support BACKWARD, FORWARD, FULL, and NONE compatibility levels - Implement Avro schema compatibility checking with field analysis - Add JSON Schema compatibility validation - Support Protobuf compatibility checking (simplified implementation) - Add type promotion rules (int->long, float->double, string<->bytes) - Integrate schema evolution into Manager with validation methods - Add schema evolution suggestions and migration guidance - Support schema compatibility validation before evolution - Add comprehensive unit tests for all compatibility scenarios Key features: ✅ BACKWARD compatibility: New schema can read old data ✅ FORWARD compatibility: Old schema can read new data ✅ FULL compatibility: Both backward and forward compatible ✅ Type promotion support for safe schema evolution ✅ Field addition/removal validation with default value checks ✅ Schema evolution suggestions for incompatible changes ✅ Integration with schema registry for validation workflows Phase G (Schema Evolution) is now complete. fmt |

Phase 5: Add Protobuf decoder support for Kafka Gateway
- Add ProtobufDecoder with dynamic message handling via protoreflect - Support Protobuf binary data decoding to Go maps and SMQ RecordValue - Implement Confluent Protobuf envelope parsing with varint indexes - Add Protobuf-to-RecordType inference with nested message support - Include Protobuf encoding for round-trip message reconstruction - Integrate Protobuf support into Schema Manager with caching - Add varint encoding/decoding utilities for Protobuf indexes - Prepare foundation for full FileDescriptorSet parsing in Phase 8 This enables the Kafka Gateway to process Protobuf-schematized messages. |
