Summary

Documents the new per-index metadata fields returned by list_indices(), and tidies the surrounding "Check Index Status" section while doing so.

Changes

  • IndexConfig metadata — document the new fields (num_indexed_rows, num_unindexed_rows, size_bytes, num_segments, index_version, created_at, index_uuid, type_url, index_details) as a compact table grouped by what each tells you, rather than a doubled snake/camelCase bullet list. Notes when they're populated vs. None/undefined.
  • Section restructure — collapse the Option 1: Check the UI / Option 2: Use the API subheadings into one flowing "Check Index Status" section, and name the UI explicitly as the LanceDB Enterprise UI.
  • Accuracy fix — the "Index" column shows an "in progress" label while a build is ongoing (verified against the sophon UI), not blank; blank means no index exists. Also dropped the unsupported "a few minutes for 1M vectors at 1536 dims" performance claim.
  • Heading fix — promote "Custom Index Names" from #### (nested under "Use the API") to a top-level section, since custom naming is a creation-time concern, not a status-checking sub-step. This also de-clutters the sidebar.

Context

Surfaces user-facing changes from the upstream feature that exposes richer per-index metadata to Python and Node.js, so users can inspect index coverage, size, and details directly from list_indices() results without a separate index_stats() call.

- Present new list_indices() metadata fields as a compact table
  instead of a doubled snake/camelCase bullet list
- Collapse the "Option 1/Option 2" subheadings into one flowing
  "Check Index Status" section and name the LanceDB Enterprise UI
- Correct the UI behavior: the "Index" column shows an "in progress"
  label while building (verified against the sophon UI), not blank
- Drop the unsupported "few minutes for 1M vectors" perf claim
- Promote "Custom Index Names" to a top-level section (it's a
  creation-time concern, not a child of "Use the API")
