In a decoupled messaging system, a producer device sends produced messages to a message fabric. The message fabric either stores the received message in designated queues, from which consumer devices may retrieve the messages, or broadcasts the messages to consumer devices that subscribe to topics assigned to the messages. A message consumption orchestrator service gathers capabilities information for the message producer, the message fabric, and the message consumer, and configures resources allocated for the message consumer to more fully optimize message throughput. Further, the message consumption orchestrator identifies patterns in changes of the rate of produced messages, i.e., through analysis of historical data and/or received information. The message consumption orchestrator configures resources for the message consumer to account for predicted need based on the identified patterns.

A mechanism is provided for controlling a process on a computing node. In one implementation, a determination is made as to whether the participation status of a computing node has changed. The participation status may, for example, be active, in which case the computing node is participating in the processing of requests from a request handler, or it may be passive, in which case the computing node is not participating in the processing of requests from the request handler. In response to a determination that the participation status of the computing node has changed from a current status to a new status, one or more processes on the computing node may be caused to begin or halt processing, in accordance with the new status. For example, if the current status is passive and the new status is active, a process on the computing node may be caused to begin processing. On the other hand, if the current status is active and the new status is passive, the process on the computing node may be caused to halt processing. Doing so helps to ensure that a process (such as a self-initiated process) executing on a passive node will not perform any processing that may lead to incorrect or inconsistent results, or even worse, to system corruption or failure.

Techniques are described for identifying unhealthy nodes in a multi-node system. One or more parameters of each node is monitored, then compared with the values for the same parameter running on other nodes in the multi-node system. Based on the comparison, a determination is made whether a node is healthy. If the multi-node system comprises one or more nodes with differing capabilities, an adjustment is performed to account for the differing capabilities of each respective node. Further provided are methods of taking remedial action upon a determination that a node is unhealthy. A tuner is used to modify values of health parameters until the node is performing similarly to its peers.
