Any tips for debugging slow queries? I was stress testing my cluster, and noticed a behavior where when I send a bunch of queries at once, the query latency goes from ~100ms to 4-5 seconds. The latency then stays relatively high for a few minutes after the stress test and then returns back to ~100ms. I also noticed behavior where sometimes a single server would take significantly longer to process a query, which ends up increasing the overall latency by a lot. That one slow server also stays consistently slow for a while, so every query is bottlenecked by that server. Thanks!

This might be a good start: https://docs.pinot.apache.org/basics/getting-started/troubleshooting-pinot#how-do-i-debug-a-slow-query-or-a-query-which-keeps-timing-out

@User Hi. I'm seeing similar issue on concurrent queries. Do you have any progress on how to solve it ?
