• Features:
  • Connection pooling via generic-pool
  • Stream query support
  • Batch inserts (1000 rows per batch)
  • 64-character table name validation
  • No foreign key support (Doris limitation)
  • Default port 9030 (Doris FE query port)
• Register driver in DriverDependencies and DatabaseType
• Map to MysqlQuery dialect in QueryBuilder
• Add unit tests and integration test infrastructure

Pull request overview

This PR adds Apache Doris database driver support to Cube.js. Doris is a MySQL protocol-compatible database, so the driver leverages the existing mysql npm package with Doris-specific adaptations. Key features include connection pooling, streaming queries, batch inserts (1000 rows per batch), and support for Doris-specific types (LARGEINT, DATEV2, DATETIMEV2, STRING) alongside MySQL-compatible types.

• New @cubejs-backend/doris-driver package with full driver implementation
• Integration with Cube.js infrastructure (driver registration, query builder mapping)
• Comprehensive test suite including unit tests, smoke tests, and driver test suite integration
