Multiple Loader Nodes - Aster Client

The Aster Loader Tool supports the use of many Aster Loader nodes. For most loading tasks, the queen is sufficient to handle all loading, but for high volume loading, you can add dedicated loader nodes to your cluster.

To use a loader node, you invoke one or more ncluster_loader instances that will load through that loader node. You may run many ncluster_loader sessions in parallel against one loader node, and you may use many loader nodes in parallel (with each node handling loads from a number of ncluster_loader instances).

To do this, you invoke each ncluster_loader instance with the -l (and optionally -f) argument to specify the loader node. The required flags are:

• as always, the --hostname option (-h) provides the queen IP address;
• the --loader flag (-l) provides the IP address of the desired loader node; and
• Optionally, the --force-loader flag (-f) forces the use of the desired loader node.
