If the thing is the number of queued and turned down threads raising steadily, you might want to consider slowing down the rate of requests (if at all possible), escalating the number of processors on your nodes, or growing the volume of nodes in the cluster.

This contains, as an example, having an average of all components, or computing the sum of all entries. Min/Max are also practical for catching outliers in details. Percentile ranks is often handy for visualizing the uniformity of information.
Client nodes: When you set node.grasp and node.data to Wrong, you'll end up having a client node, and that is made to work as a load balancer that helps route indexing and search requests. Client nodes assistance shoulder a lot of the search workload to make sure that facts and primary-suitable nodes can concentration on their own core tasks.
