| 643510821 | MDU6SXNzdWU2NDM1MTA4MjE= | 862 | Set an upper limit on total facet suggestion time for a page | 9599 | open | 0 | 1 | 2020-06-23T03:57:55Z | 2020-06-23T03:58:48Z | OWNER | If a table has 100 columns the facet suggestion code will currently run 100 times, taking a max of `facet_suggest_time_limit_ms` which defaults to 50ms per column: https://github.com/simonw/datasette/blob/000528192eaf891118932250141dabe7a1561ece/datasette/facets.py#L142-L162 So for 100 columns, that's 100 * 50ms = 5s total time that might be spent attempting to calculate facets on a large table! I should implement a hard upper limit on the total amount of time taken suggesting facets - probably of around 500ms. If it takes longer than that the remaining columns will not be considered. | 107914493 | issue | {"url": "https://api.github.com/repos/simonw/datasette/issues/862/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} |
