> Context: IMAP4rev1 (RFC3501 requires that every message is identified by a stable 32-bit
Unique Identifier (UID) assigned in incremental sequence. This is now achieved in James IMAP
subproject (http://james.apache.org/imap) with a UidProvider interface implemented in memory.
This implementation does not allow distributed working of the solution.
> Task: A DistributedUidProvider must be designed. The design can rely on a distributed
memory cache such as hazelcast , or any other solution (hadoop, hbase, cassandra,...), and
implemented.
> Mentor: eric at apache dot org
> Complexity: medium
