             Summary: [ObjectStore] New Composing ObjectStore ontop of Swift and Cassandra
                 Key: JAMES-2583
                 URL: https://issues.apache.org/jira/browse/JAMES-2583
             Project: James Server
          Issue Type: Improvement
            Reporter: Trần Tiến Đức


Why we need it?
In our production, we're using cassandra blobstore, regards to the purpose of switching to
swift blobstore, we need a kind of new BlobStore which writes new blobs to swift, read new
blobs from swift, read old blobs from cassandra.
Proposal name: JoiningObjectStore

 

Definition of Done

1. new JoiningObjectStore implements BlobStore
2. JoiningObjectStore should compose primary BlobStore and secondary BlobStore.
when reading from JoiningObjectStore, read from the primary BlobStore, if not exist, fallback
to the secondary blobstore.
similar to write.

3. test it
