Cancel running queries trigger by dashboard

[timgl]

In what situation are you experiencing subpar performance?

We don't cancel running queries triggered by dashboards, which causes performance issues

How to reproduce

1. Open dashboard/refresh
2. Navigate away
3. See queries are still running

Environment

• PostHog Cloud
• PostHog self-hosted with Kubernetes (deprecated, see "Sunsetting Kubernetes support"), version/commit: [please provide]

Additional context

Thank you for your performance issue report – we want PostHog to go supersonic!

We've talked about this in the team and decided this issue is no longer valid. For one, it dates back to when the frontend was issuing the queries, and you could actually see they are still made in the network tab.
We now have async queries on dashboards and are also reworking the cache warming. The goals are to get insights into the cache for users to see charts much more quickly. Canceling queries when the users wanted to look at a dashboard runs counter to that, we already spent some computing time, so we can just as well fill the cache.
