   Hi @askoa, yes currently we can launch a bunch of tasks in a single grpc request. However, for the same stage, they don't share the information, like execution plan, etc. 
   
   I'd like to add something like this.
   ```
   // A set of tasks in the same stage
   message MultiTaskDefinition {
     PartitionIds task_ids = 1;
     bytes plan = 2;
     string session_id = 3;
     repeated KeyValuePair props = 4;
   }
   ```
   
   Then we can not only reduce the rpc request body size, but also reduce the execution plan deserialization cost.
