The persistence layer of the Nuxeo Platform repository is configurable. Several options can be chosen depending on your scalability, integration, and performance constraints.
The repository stores:
Documents For the documents, you can either choose the VCS repository implementation that stores the data on an RDBMS, or the DBS - MongoDB implementation, that stores the data on a MongoDB document-based system.
Binaries The binary store documentation page describes the options available for storing binaries: file system, cloud-based, encrypted.
