Connector Common

Overview

core/connectors/common/ provides shared utilities used by connector implementations (Delta, Iceberg, and others). It includes stats engines, NDV helpers, planners, and auth helpers that implementations reuse rather than duplicate.

Where It Fits

  • Connector SPI – Interfaces live in docs/connectors-spi.md.
  • Connector Implementations – Iceberg and Delta implementations call into the shared helpers when generating stats or planning scans.
