The multi-logstash pipeline setup, while amazingly fast, was crashing and causing index errors when under high load for a long period of time. Because of the crashing behavior and the fact that the folks from Elastic describe multi-pipeline queues to be "beta" at this time the logstash pipelines have been converted back into a single pipeline. The memory backed queue options are now limited by a ram disk (tmpfs) which will ensure that a burst within the queue does not cause OOM issues and ensures a highly performant deployment and limiting memory usage at the same time. Memory backed queues will be enabled when the underlying system is using "rotational" media as detected by ansible facts. This will ensure a fast and consistent experience across all deployment types. Pipeline/ml/template/dashboard setup has been added to the beat configurations which will ensure beats are properly configured even when running in an isolated deployment and outside of normal operations where beats are generally configured on the first data node.
