MongoDB Atlas has introduced a feature called Analytics Nodes to power Business Intelligence (BI) workloads in its cloud managed service. These nodes allow for dedicated handling of analytics workloads within MongoDB clusters, isolating them from the operational workload and improving performance. By adding an Analytics node to a cluster and setting the read preference to target it, users can isolate their analytical queries from the rest of the workload, making it ideal for BI Connectors. Additionally, Atlas replica set tags enable further customization of query behavior, allowing users to direct traffic to specific regions or nodes based on their needs.
