@item scale horizontally (no brokers, seamlessly add more nodes to the
cluster)
@item low-latency push based message delivery (performance)
@item combine load-balanced and multicast style message routing
@item excel at both streaming (high-throughput) and job oriented
(low-throughput) workloads
@item primarily in-memory (beyond a high-water mark messages are transparently
kept on disk)
@item runtime discovery service for consumers to find producers (nsqlookupd)
@item transport layer security (TLS)
@item data format agnostic
@item few dependencies (easy to deploy) and a sane, bounded, default
configuration
@item simple TCP protocol supporting client libraries in any language
@item HTTP interface for stats, admin actions, and producers (no client
library needed to publish)
@item integrate with @acronym{StatsD, Stats aggregation Daemon} for realtime
instrumentation
@item robust cluster administration interface (nsqadmin)

It achieves maximum availability for your cluster services (a.k.a. resources) by

the messaging and membership capabilities provided by Corosync.

It can do this for clusters of practically any size and comes with a powerful
dependency model that allows the administrator to accurately express the
relationships (both ordering and location) between the cluster resources.

Virtually anything that can be scripted can be managed as part of a Pacemaker cluster.")
