Enhanced MQ publishers to utilize the new logical types:
- Updated convertToRecordValue() to use TimestampValue instead of string RFC3339
- Added DateValue support for birth_date field (days since epoch)
- Added DecimalValue support for precise_amount field with configurable precision/scale
- Enhanced UserEvent struct with PreciseAmount and BirthDate fields
- Added convertToDecimal() helper using big.Rat for precise decimal conversion
- Updated test data generator to produce varied birth dates (1970-2005) and precise amounts
Publishers now generate structured data with proper logical types:
- ✅ TIMESTAMP: Microsecond precision UTC timestamps
- ✅ DATE: Birth dates as days since Unix epoch
- ✅ DECIMAL: Precise amounts with 18-digit precision, 4-decimal scale
Successfully tested with PostgreSQL integration - all topics created with logical type data.
- Remove github.com/pganalyze/pg_query_go/v6 dependency to avoid CGO requirement
- Implement lightweight SQL parser for basic SELECT, SHOW, and DDL statements
- Fix operator precedence in WHERE clause parsing (handle AND/OR before comparisons)
- Support INTEGER, FLOAT, and STRING literals in WHERE conditions
- All SQL engine tests passing with new parser
- PostgreSQL integration tests can now build without CGO
The lightweight parser handles the essential SQL features needed for the
SeaweedFS query engine while maintaining compatibility and avoiding CGO
dependencies that caused Docker build issues.
The pg_query_go library requires CGO to be enabled as it wraps the libpg_query C library.
Added gcc and musl-dev dependencies to the Docker build for proper compilation.
