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:

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}",,
