ERROR: canceling statement due to user request


If you see this error message in your query log, it means that the running query has been cancelled. This can happen for one of two reasons:

  1. The query was manually cancelled, either from the Data Explorer or the Query Log.
  2. The query exceeded the Maximum Query Duration setting for your data source.

Generally, it’s a good idea to keep the Maximum Query Duration set to less than 5 minutes. Any queries which consistently take longer than 5 minutes should be optimized, because they tie up database resources and can prevent other charts from loading.

For general tips on optimizing query performance, see our Help Center article.
