The Main Stores - Alfresco Content Services - 23.4 - 23.4 - Ready - Alfresco - external

• The Working Store (workspace://SpacesStore) contains the metadata for all active/live nodes in the Repository. This store is implemented using a database (RDBMS).
• The Content Store contains the physical files uploaded to the Repository and is located in the {Alfresco install dir}/alf_data/contentstore directory on the filesystem by default, but can also be configured to use other storage systems, for example, Amazon S3. It is also possible to define content store policies for storing files on different storage systems, effectively defining more than one physical content store.
• Whenever a node is deleted, the metadata for the node is moved to the Archive Store (archive://SpacesStore), which uses the configured database. The physical file for a deleted node is moved (by default after 14 days) to the {Alfresco install dir}/alf_data/contentstore.deleted directory, where it stays indefinitely. However, a clean-up job can be configured to remove the file at a certain point in time (referred to as eager clean-up).
• When the versionable aspect is applied to a node, a version history is created in the Version Store (workspace://version2Store). Versioned node metadata is stored in the database and files remain in the {Alfresco install dir}/alf_data/contentstore directory. Versioning is not applicable to folder nodes.
• The System Store is used to save information about installed Alfresco Content Services extension modules.
