Data Management

These document introduce data management practices and strategies for MongoDB deployments, including strategies for managing multi-data center deployments, managing larger file stores, and data lifecycle tools.

Data Center Awareness
Presents the MongoDB features that allow application developers and database administrators to configure their deployments to be more data center aware or allow operational and location-based separation.
Capped Collections
Capped collections provide a special type of size-constrained collections that preserve insertion order and can support high volume inserts.
Expire Data from Collections by Setting TTL
TTL collections make it possible to automatically remove data from a collection based on the value of a timestamp and are useful for managing data like machine generated event data that are only useful for a limited period of time.
