Issue with DataStream action in Paris : Execution time is much higher compared to OrlandoDescriptionDataStream action execution in Paris may be be several times slower than in Orlando. A new feature was added to Paris to optimize memory usage during execution of very large flows. This feature did not take into account that flows with DataStream actions already have memory optimization and so unnecessary, time consuming database persistence occurs during DataStream actions.Steps to Reproduce Execute the same flow with a DataStream action in both Orlando and Paris and observe the execution time difference. Alternatively, 1) Execute a flow with a DataStream action and observe the execution time. 2) Set system property "com.glide.hub.flow_engine.op_executions_between_saves" to "-1". (This will disable a feature that is new to Paris) 3) Execute the same flow again and observe the execution time is much quicker.WorkaroundSet system property "com.glide.hub.flow_engine.op_executions_between_saves" to "-1".Related Problem: PRB1453173
