Data Center Awareness
On this page
MongoDB provides a number of features that allow application developers and database administrators to customize the behavior of a sharded cluster or replica set deployment so that MongoDB may be more "data center aware," or allow operational and location-based separation.
MongoDB also supports workload isolation based on functional parameters, to ensure
mongod instances are only used for reporting workloads
or that certain high-frequency portions of a sharded collection only exist on
The following documents, found either in this section or other sections of this manual, provide information on customizing a deployment for operation- and location-based separation:
- Workload Isolation in MongoDB Deployments
- MongoDB lets you specify that certain application operations use
- A zone represents one or more ranges of shard key values for a sharded collection. MongoDB routes reads and writes for sharded data covered by a zone only to shards inside that zone. For use in managing data distribution and deployment patterns.
- Manage Shard Zones
- Administrative tasks related to configuring zones in sharded clusters
The Write Concern and Read Preference documents, which address capabilities related to data center awareness.
