[GitHub] [pinot] ankitsultana opened a new issue, #10331: [multistage] Fix Bottlenecks in QueryDispatcher
ankitsultana opened a new issue, #10331:
URL: https://github.com/apache/pinot/issues/10331
There are the following issues with QueryDispatcher right now:
1. There's no timeout set for the dispatch call. This can lead to a query getting stuck indefinitely until the connection is terminated on the client-side.
2. The dispatch calls are made sequentially. For queries with high parallelism and large number of stages, this can add 5-10s of query latency overhead.
3. The payload sent in the dispatch call is quite large. We send the entire stage metadata map for each dispatch call.
