Goal** + +To provide a SQL querying interface for SeaweedFS, enabling analytics on existing MQ topics.

Data Source Integration** + +* **MQ Topic Connector (Primary):** + * Build on existing `weed/mq/logstore/read_parquet_to_log.go` + * Implement efficient Parquet scanning with predicate pushdown + * Support schema evolution and backward compatibility + * Handle partition-based parallelism for scalable queries +* **Schema Registry Integration:** + * Extend `weed/mq/schema/schema.go` for SQL metadata operations + * Read existing topic schemas for query planning + * Handle schema evolution during query execution + +**4. API & CLI Integration** + +* **CLI Command:** + * New `weed sql` command with interactive shell mode (similar to `weed shell`) + * Support for script execution and result formatting + * Connection management for remote SeaweedFS clusters +* **gRPC API:** + * Add SQL service to existing MQ broker gRPC interface + * Enable efficient query execution with streaming results + +## Example Usage Scenarios + +**Scenario 1: Schema Discovery and Metadata** +```sql +-- List all namespaces (databases) +SHOW DATABASES; + +-- List topics in a namespace +USE my_namespace; +SHOW TABLES; + +-- View topic structure and discovered schema +DESCRIBE user_events; +``` + +**Scenario 2: Data Querying** +```sql +-- Basic filtering and projection +SELECT user_id, event_type, timestamp +FROM user_events +WHERE timestamp > 1640995200000 +LIMIT 100; + +-- Aggregation queries +SELECT COUNT(*) as event_count +FROM user_events +WHERE timestamp >= 1640995200000; + +-- More aggregation examples +SELECT MAX(timestamp), MIN(timestamp) +FROM user_events; +``` + +**Scenario 3: Analytics & Monitoring** +```sql +-- Basic analytics +SELECT COUNT(*) as total_events +FROM user_events +WHERE timestamp >= 1640995200000; + +-- Simple monitoring +SELECT AVG(response_time) as avg_response +FROM api_logs +WHERE timestamp >= 1640995200000; + +## Architecture Overview + +``` +SQL Query Flow: + 1.
