Description

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.

Complexity: medium
