**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. **Describe the solution you'd like** A clear and concise description of what you want to happen. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
