Abstract
Introduction
In Adobe Experience Manager (AEM), binary data can be stored independently from the content nodes. The binary data is stored in a data store, whereas content nodes are stored in a node store.
Both data stores and node stores can be configured using OSGi configuration. Each OSGi configuration is referenced using a persistent identifier (PID).
Data Store Configurations
When dealing with large number of binaries, it is recommended that an external data store be used instead of the default node stores in order to maximize performance.
For example, if your project requires a large number of media assets, storing them under the File or S3 Data Store will make accessing them faster than storing them directly inside a MongoDB.
The File Data Store provides better performance than MongoDB, and Mongo backup and restore operations are also slower with large number of assets.
Amazon S3 Data Store
AEM can be configured to store data in Amazon's Simple Storage Service (S3). It uses the org.apache.jackrabbit.oak.plugins.blob.datastore.S3DataStore.config PID for configuration.
In order to enable the S3 data store functionality, a feature pack containing the S3 Datastore Connector needs to be downloaded and installed. Go to the Adobe Repository and download the latest version from the 1.10.x versions of the feature pack (for example, com.adobe.granite.oak.s3connector-1.10.0.zip). Additionally, you also need to download and install the latest AEM service pack as listed on the AEM 6.5 Release Notes page.
