Data Center Awareness¶
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 segregation based on functional parameters, to ensure that certain mongod instances are only used for reporting workloads or that certain high-frequency portions of a sharded collection only exist on specific shards.
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:
- Operational Segregation in MongoDB Deployments
- MongoDB lets you specify that certain application operations use certain mongod instances.
- Tag Aware Sharding
- Tags associate specific ranges of shard key values with specific shards for use in managing deployment patterns.
- Manage Shard Tags
- Use tags to associate specific ranges of shard key values with specific shards.
