No games for August 2023 (+September 2023?) #241

Closed AAArmstark closed 1 year ago

It was first reported here and I couldn't find an explanation for it (maybe it takes some time to update on the 1st of a month or whatever) and thought it's better to report it.

Steps to reproduce:

  1. Go to opening explorer
  2. In the settings, select "Lichess database"
  3. Set "Since" to "August 2023"
  4. Set "Until" to "August 2023" or "September 2023"
  5. Check that every rating/time control is selected
  6. "No game found" message showing up

Hi, yes, this is expected. To explain:

The process is currently to wait for the export of the month on https://database.lichess.org/, followed by downloading and importing the database dump on the opening explorer server. The opening explorer server has just enough I/O throughput to handle requests at peak time, so the import process is throttled to avoid putting too much load on it. All in all games can be up to 6 weeks late.

The same is not true for the "personal"/player, which is updated on demand but almost immediately.

Thanks for the detailed answer and sorry for taking up your time!
