Dataset Viewer rebuild remains pending after schema metadata update

#10
by maxwellinked - opened

@lhoestq ? the production Dataset Viewer cache for this dataset has remained unavailable after merging a schema-only metadata correction.

  • Current main commit: 9aa0bacc6f37f64e2568d2203bd8f369e764c927
  • Change: explicit, identical 29-field features declarations for the canonical and pre_standard VideoFolder configs; no media files changed
  • Independent datasets==4.8.4 streaming test at that exact revision passes: canonical/archive = 338 rows, pre_standard/archive = 129 rows; both expose encoded_frame_rate as float64
  • Public Viewer endpoints /splits, /is-valid, /parquet, /size, and /rows all currently return HTTP 500: ?The server is busier than usual and the response is not ready yet. Please retry later.?
  • The prior build completed successfully before this corrective metadata merge.

Could you please inspect or retrigger the Viewer job for the current main revision? I am deliberately withholding the planned v0.3.0 tag until the production Viewer/Parquet output is verified.

Update: the rebuild has partially recovered, which narrows the problem.

At 2026-08-18 21:51 UTC:

  • /is-valid returns 200 with preview, viewer, search, and filter all true (statistics remains false).
  • /rows returns 200 for both canonical/archive and pre_standard/archive, including their last rows. Live totals are 338 and 129, partial: false, 29 fields in both, and encoded_frame_rate is now correctly float64. This confirms row serving is using the corrected 9aa0bacc... schema.
  • /splits, /parquet, and /size still return HTTP 500 with x-error-code: ResponseNotReady.
  • The public Hugging Face status feed shows no active incident.

This now looks like a stuck or incomplete dataset-specific split/Parquet aggregation job rather than a general outage. The v0.3.0 tag remains withheld pending those three outputs.
