Configuring Throttling

Although balancing storage pool disk space use is important, it requires network, computation, and disk bandwidth that must be shared with other functions. Hence, the number of container moves at any point of time is throttled. By default, the maximum number of container moves is 10% of the number of nodes in the cluster. However, you can configure the throttling factor (percentage) by setting the parameter cldb.balancer.disk.max.switches.in.nodes.percentage using the maprcli command.

For example, to reset the throttling factor to 12% of the number of nodes in the cluster, run the following command:

maprcli config save -values {"cldb.balancer.disk.max.switches.in.nodes.percentage":"12"}
