Tuning Tuple Mover Pool Settings

Scenario

During loads, you occasionally notice spikes in the number of ROS containers, and you would like to make the Tuple Mover more aggressive.

Solution

Increase MAXCONCURRENCY in the TM pool to 3 or higher. This setting enables the Tuple Mover to run multiple mergeout threads. If a large mergeout is in progress, smaller ROS containers can be merged, which helps minimize buildup of ROS containers, and avoid ROS pushback.
