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 the MAXCONCURRENCY parameter of the TM pool to 3 or higher. This setting ensures that the Tuple Mover can run more than one mergeout thread, so if a large mergeout is in progress, smaller ROS containers can also be merged, thus preventing a buildup of ROS containers.
