The Eclipse Ditto teams is proud to announce the availability of Eclipse Ditto 3.4.0.

Version 3.4.0 mainly concentrates on exchanging the use of the Akka toolkit (due to a change in licensing) with its fork Apache Pekko which remains Apache 2.0 licensed.
Apart from that, several improvements are also included which can be found in the changelog.

Adoption

When you use Eclipse Ditto it would be great to support the project by putting your logo there.

Changelog

The main improvements and additions of Ditto 3.4.0 are:

Eclipse Ditto 3.4.0 focuses on the following areas:

  • Supporting HTTP POST for performing searches with a very long query
  • Addition of a new placeholder to use in connections to use payload of the thing JSON e.g. in headers or addresses
  • New placeholder functions for joining multiple elements into a single string and doing URL-encoding and -decoding
  • Configure MQTT message expiry interval for published messages via a header
  • Reduce patch/merge thing commands to modify only the actually changed values with a new option
  • UI enhancements:
    • Adding sending messages to Things
    • Made UI (at least navigation bar) responsive for small screen sizes
    • Increase size of JSON editors in “edit” mode

The following non-functional work is also included:

  • Swapping the Akka toolkit (because of its switch of license to BSL License after Akka v2.6.x) with its fork Apache Pekko which remains Apache 2.0 licensed.
  • Support for using AWS DocumentDB as a replacement for MongoDB
  • Improve logging by adding the W3C Trace Context traceparent header as MDC field to logs
  • Adjust handling of special MQTT headers in MQTT 5
  • Optimize docker files
  • Migration of Ditto UI to TypeScript
  • There now is an official Eclipse Ditto Benchmark which shows how Ditto is able to scale horizontally and provides some tuning tips
  • Addition of a benchmark tooling to run own Ditto benchmarks

The following notable fixes are included:

  • Fixed that failed retrieval of a policy (e.g. after policy change) leads to search index being “emptied out”
  • Fixed that putting metadata when updating a single scalar value did not work
  • UI fix, fixing that patching a thing will null values did not reflect that change in the UI

Please have a look at the 3.4.0 release notes for a more detailed information on the release.
