Description
Current, other than vector index, both scalar indices and full text indices do not expose friendly API to be integrated into distributed frameworks.
We could start to have a ScalarIndexWriter which writes (value, row_id) streams into btree/bitmap indices. In this way, we can use external frameworks like Ray or Spark to do distributed sorting.

Research direction
No files or tests are named. Start by reviewing the existing vector-index implementation and the scalar and full-text index interfaces, then clarify the proposed Python API and its integration boundary. Done should mean a ScalarIndexWriter can consume (value, row_id) streams and write btree or bitmap indices for external distributed frameworks.
