Cluster Introduction
The Open Access cluster is the bridge between your code and the data available from various ITRS products. It consists of a number of processes, potentially running across multiple machines.
Configuration is maintained distributed across all nodes and specifies which Gateway2 instances to connect to. The gateway connections are then spread across the nodes. (See Gateway Distribution)
An API client can connect to any of the nodes in the cluster and submit a query. The query is distributed across all nodes and data matching the query is returned directly to the client.
New nodes can join at any time. Once the joining is complete, the Gateway2 connections are redistributed across the cluster.
The cluster is also resilient against Node failure.
