An off-the-shelf Alfresco installation is using the file system to store
its content binaries. However, it is possible to configure Alfresco with
another content store, e.g. a Caringo Swarm cluster (cfr.
http://www.caringo.com) or an S3-compatible content store (most known in
this category being AWS S3). When Alfresco stores a file in a Caringo
Swarm cluster, it will receive a reference to the file in the format
swarm://swarmClusterName/[bucket-name>]/[UUID].bin. This is the
contentUrl that is stored in the Alfresco database. For an S3 content
store, it is TO BE COMPLETED.
