Phase 2: Implement CreateTopics protocol compliance for v0/v1
CreateTopics Protocol Compliance completed: ## Implementation - Implement handleCreateTopicsV0V1() with proper v0/v1 request parsing - Support regular array/string format (not compact) for v0/v1 - Parse topic name, partitions, replication factor, assignments, configs - Handle timeout_ms and validate_only fields correctly - Maintain existing v2+ compact format support - Wire to SeaweedMQ handler for actual topic creation ## Key Features - Full v0-v5 CreateTopics API version support - Proper error handling (TOPIC_ALREADY_EXISTS, INVALID_PARTITIONS, etc.) - Partition count validation and enforcement - Compatible with existing SeaweedMQ topic management ## Tests - Comprehensive unit tests for v0/v1/v2+ parsing - Error condition testing (duplicate topics, invalid partitions) - Multi-topic creation support - Integration tests across all API versions - Performance benchmarks for CreateTopics operations ## Verification - All protocol tests pass (v0-v5 CreateTopics) - E2E Sarama tests continue to work - Real topics created with specified partition counts - Proper error responses for edge cases Ready for Phase 3: ApiVersions matrix accuracy

# Kafka Gateway Implementation Phases
|
||||
|
||||
## Phase 1: Core SeaweedMQ Integration (PRIORITY HIGH)
|
||||
## Phase 1: Core SeaweedMQ Integration (COMPLETED ✅)
|
||||
**Goal**: Enable real message retrieval from SeaweedMQ storage
|
||||
|
||||
### Tasks:
|
||||
- [ ] Implement `integration.SeaweedMQHandler.GetStoredRecords()` to return actual records
|
||||
- [ ] Add proper SMQ record conversion from SeaweedMQ format to Kafka format
|
||||
- [ ] Wire Fetch API to use real SMQ records instead of synthetic batches
|
||||
- [ ] Add integration tests for end-to-end message storage and retrieval
|
||||
- [x] Implement `integration.SeaweedMQHandler.GetStoredRecords()` to return actual records
|
||||
- [x] Add proper SMQ record conversion from SeaweedMQ format to Kafka format
|
||||
- [x] Wire Fetch API to use real SMQ records instead of synthetic batches
|
||||
- [x] Add integration tests for end-to-end message storage and retrieval
|
||||
|
||||
**Files to modify**:
|
||||
**Files modified**:
|
||||
- `weed/mq/kafka/integration/seaweedmq_handler.go`
|
||||
- `weed/mq/kafka/protocol/fetch.go` (verification)
|
||||
- Add test file: `weed/mq/kafka/integration/record_retrieval_test.go`
|
||||
- Added test file: `weed/mq/kafka/integration/record_retrieval_test.go`
|
||||
|
||||
**Verification**: E2E tests show "Found X SMQ records" - real data retrieval working
|
||||
|
||||
## Phase 2: CreateTopics Protocol Compliance (PRIORITY HIGH)
|
||||
**Goal**: Fix CreateTopics API parsing and partition handling
