High-performance data dissemination server.

A light-weight SDMX data and metadata REST API server designed to be deployed in clusters in the DMZ or at the network edge for scalable, fault-tolerant public data dissemination use cases.

A typical configuration consists of a private Fusion Registry Core installation and a cluster of between two and four Fusion Edge Servers that drive the actual dissemination services such as web data portals and public APIs. Data is published for dissemination by exporting a ZIP file from the Fusion Registry Core containing all of the data and structures. The ZIP file is pushed to each of the Fusion Edge Servers using any suitable means like FTP or WebDAV. On receipt, the Edge Servers load the new data and start serving it, either immediately or at a defined time.

No database is required.
Once primed with data, Fusion Edge Servers are completely autonomous requiring no connection back through the firewall to services on the private network.
