I started working on this today (https://github.com/apache/incubator-superset/commit/bf0025f687fef0f75f660d384a5559ad5d3ed7c9), but I don't think it makes a lot of sense to add a backoff within Superset if pyhive only supports constant polling intervals. Therefore, I have a few options, ranked in my preference order: 1. Update the sleep within handle_cursor to be equal to the poll_interval configured in the presto database's `engine_params` object. then both params will be aligned and fully configurable by the admin 2. Open a PR against pyhive to support using a generator function as well as a constant value for `poll_interval`, then update Superset to default to some variety of fibo backoff for both 3. Manually update the constant sleep value in Superset to something smaller than 1 (maybe 0.5 for now) and also default the presto engine params to also send 0.5. This isn't configurable, but it would have immediate performance improvements @john-bodley @bkyryliuk @ktmud @villebro @tooptoop4, thoughts? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
