M3 Query, a stateless query server for M3DB and Prometheus
M3 Query is a service that exposes all metrics query endpoints along with metrics time series metadata APIs that return dimensions and labels of metrics that reside in a M3DB cluster.
Note: M3 Coordinator, and by proxy M3DB, by default includes the M3 Query endpoints accessible on port 7201. For production deployments it is recommended to deploy it as a dedicated service to ensure you can scale the memory heavy query role separately from the metrics ingestion write path of writes through M3 Coordinator to M3DB database role nodes. This allows excessive queries to primarily affect the dedicated M3 Query service instead of interrupting service to the write ingestion pipeline.
