Phase 1: Enhanced Kafka Gateway Schema Integration
Phase 1: Enhanced Kafka Gateway Schema Integration
- Enhanced AgentClient with comprehensive Kafka record schema - Added kafka_key, kafka_value, kafka_timestamp, kafka_headers fields - Added kafka_offset and kafka_partition for full Kafka compatibility - Implemented createKafkaRecordSchema() for structured message storage - Enhanced SeaweedMQHandler with schema-aware topic management - Added CreateTopicWithSchema() method for proper schema registration - Integrated getDefaultKafkaSchema() for consistent schema across topics - Enhanced KafkaTopicInfo to store schema metadata - Enhanced Produce API with SeaweedMQ integration - Updated produceToSeaweedMQ() to use enhanced schema - Added comprehensive debug logging for SeaweedMQ operations - Maintained backward compatibility with in-memory mode - Added comprehensive integration tests - TestSeaweedMQIntegration for end-to-end SeaweedMQ backend testing - TestSchemaCompatibility for various message format validation - Tests verify enhanced schema works with different key-value types This implements the mq.agent architecture pattern for Kafka Gateway, providing structured message storage in SeaweedFS with full schema support.pull/7231/head
