[GitHub] [arrow-ballista] Ted-Jiang opened a new issue, #748: [Improvement] Increase the throughput in push-staged TaskSchedulingPolicy

Ted-Jiang opened a new issue, #748:
URL: https://github.com/apache/arrow-ballista/issues/748

   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   Our team using `push-staged` TaskSchedulingPolicy as the OLAP query engine,  we main focus on the quick respond query less than `10s`  hundreds degrees of concurrency. 
   
   Now: 
   
   `Cluster`: with 60 executor (each 200 slots) and 1 scheduler cluster.
   `WorkLoad`: 200 clients submit 0.5s cost query in sequence.
   
   We got 1200 query per mins 😢 
   
   So we found below issues in `push-staged`
   
   - Should wait for the launch_multi_task result asynchronously
   - Try avoid data lock racing
   - Avoid empty events and combine continuous events
   - etc
   
   After fix these we got 16000 query per mins  ! We will contribute these back soon.
