* `VALUES` aggregate function can run for a long, long time when collecting many, many groups. Hundreds of thousands of groups can run on one thread for many minutes and millions of groups run for days. It is O(n^2^) with the number of groups. These will not respond to the tasks cancellation API the whole time. Fixed by {es-pull}#123073[#123073] and available in 8.16.5, 8.17.3, 8.18.0, and all releases after that.
