Class AggregatingContentStore

  • All Implemented Interfaces:
    org.alfresco.repo.content.ContentStore
    public class AggregatingContentStore
extends AbstractContentStore

    Aggregating Content Store

    A content store implementation that aggregates a set of stores. Content is not persisted by this store, but rather it relies on any number of child stores to provide access to content readers and writers.

    The order in which the stores appear in the list of stores participating is important. The first store in the list is known as the primary store.

    Content is written to the primary store only. The other stores are only used to retrieve content and the primary store is not updated with the content.
