Summary

Prototype of low level ("storage") write interface, and implementations for iceberg and deltacat

This PR only includes the low level ("storage") write interface, which Daft or other query engines can integrate with, not the higher level ("catalog") user-facing interface.

Subsequent PRs will prototype Daft integration and flesh out higher level user-facing interfaces. See README in data access layer module for more details

Changes

  • Fix minor bugs in rivulet and deltacat schema class
  • Introduce dataset writer interface and implement for rivulet and iceberg

Testing

Unit tests
