Performance

  • JAMES-3295 Multiple IMAP performance enhancements for the Distributed Server. Some enhancement might transfer to other servers as well.
    • JAMES-3295 Use MessageManager::listMessagesMetadata more widely (IMAP)
    • JAMES-3265 IMAP FETCH reading lastUid and lastModseq should be optional

  • JAMES-2037 Use Flux for MessageManager::search
  • JAMES-3409 Better denormalize mailboxes within the Distributed Server. This enables reading only one table of the projection instead of two. Read repairs are implemented for keeping eventual consistency checks. Read upgrade instructions.
  • JAMES-3433 Distributed Server: use caching blobstore only for frequently accessed data (callers can specify the level of performance they expect). This ensures the cache is read when it is useful.
  • JAMES-3408 Limit concurrency when retrieving mailbox counters
  • JAMES-3430 Restructure message properties storage within Cassandra Mailbox. See upgrade instructions.
  • JAMES-3277 SetMessagesUpdateProcessor should read less mailboxes - enhance performance for JMAP-draft and JMAP RFC-8621.
  • JAMES-3408 Enforce IMAP List not reading counters for Distributed James
  • JAMES-3377 Remove unused text criterion - newly indexed mails indexed in ElasticSearch will take less space
  • JAMES-3095 Avoid listing all subscriptions for each mailbox (IMAP)
  • JAMES-2629 Use a future supplier in CassandraAsyncExecutor
  • JAMES-2904 Avoid loading attachment when not needed (IMAP & JMAP) + attachment content streaming (JMAP)
  • JAMES-3155 Limit the number of flags updated at the same time
  • JAMES-3264 MAILBOX details are read 3 times upon indexing
  • JAMES-3506 Avoid a full body read within VacationMailet

[3.5.0] - 2020-04-06

Added

  • JAMES-2813 task management for Distributed James product. This enables several James servers to share a consistent view of tasks being currently executed.
  • JAMES-2563 Health check for ElasticSearch
  • JAMES-2904 Authentication and SSL support for Cassandra backend

  • Removed unnecessary fields from mailbox mapping
  • Disable dynamic mapping thanks to a change of the header structure
  • Multiple changes have been made to enhance Distributed James indexing performance:
    • JAMES-2917 Use of routing keys to collocate documents per mailbox
    • JAMES-2910 Under some configuration, html was not extracted before document indexing
    • JAMES-2079 Removed unnecessary fields from mailbox mapping

  • Usernames are assumed to be always lower cased. Many users recently complained about mails non received when sending to upper cased local recipients. We decided to simplify the handling of case for local recipients and users by always storing them lower cased.
  • JAMES-2576 Unhealthy health checks now return HTTP 503 instead of 500, degraded now returns 200 instead of 500. See JAMES-2576.
  • JAMES-2992 In order to fasten JMAP-draft message retrieval upon calls on properties expected to be fast to fetch, we now compute the preview and hasAttachment properties asynchronously and persist them in Cassandra to improve performance. See JAMES-2919.
  • JAMES-2950 It is now forbidden to create new Usernames with the following set of characters in its local part : "(),:; <>@\[], as we prefer it to stay simple to handle. However, the read of Usernames already existing with some of those characters is still allowed, to not introduce any breaking change. See JAMES-2950.
  • JAMES-3040 Linshare blob export configuration and mechanism change.
  • JAMES-3112 Differentiation between domain alias and domain mapping. Read upgrade instructions.
  • JAMES-3122 Log4J2 adoption for Spring product. Log file configuration needs to be updated. See upgrade instructions.

Removed

  • Classes marked as deprecated whose removal was planned after 3.4.0 release (See JAMES-2703). This includes:
    • SieveDefaultRepository. Please use SieveFileRepository instead.
    • JDBCRecipientRewriteTable, XMLRecipientRewriteTable, UsersRepositoryAliasingForwarding, JDBCAlias mailets. Please use RecipientRewriteTable mailet instead.

  • JAMES-3122 LogEnabled API in Spring product had been removed for Log4J2 adoption for Java 9+ runtime compatibility.
  • HybridBlobStore. This will be removed after 3.6.0 release. Introduced to fasten small blob access, its usage could be compared to a cache, but with a sub-optimal implementation (no eviction, default replication factor, no circuit breaking). Use BlobStore cache instead.

Third party softwares

  • The distributed James server product (relying on Guice, Cassandra, ElasticSearch, RabbitMQ and optionally Swift) now needs at least RabbitMQ 3.8.1.
