Eclipse Ditto 2.0.0 contains the following API breakages:
- Removal of API version 1 (from HTTP and all Java APIs), deprecated in Ditto 1.1.0
- Removal of public Java APIs marked with @Deprecated
- Restructurization of Ditto's maven modules in order to simplify/ease further development
It includes the following topics/enhancements:
- Merge/PATCH updates of digital twins
- Configurable OpenID Connect / OAuth2.0 claim extraction to be used for authorization
- Establishing connections to endpoints (via AMQP, MQTT, HTTP) utilizing a Ditto managed SSH tunnel
- Addition of a DevOps API in order to retrieve all known connections
- Expiring policy subjects + publishing of notification message prior to expiry
- Built-in acknowledgement for search updates to have the option of twin updates with strong consistency of the search index
- Addition of policy actions in order to inject a policy subject based on a provided JWT
- Restoring active connection faster after a hard restart of the Ditto cluster via automatic prioritization of connections
- Support for LastWill/Testament + retain flag for MQTT connections
- Provide JWT tokens to Websocket endpoint with browser APIs
The following notable fixes are included:
- Fixing that "content-type" of a Ditto Protocol JSON message describes the content of the "value" of the message
- Fixing password encoding/decoding for AMQP 1.0 connections when special characters like "+" were used
- Fix merging "extraFields" into thing payload when using "normalization" mapper in connections
The following non-functional work is also included:
- Improvement of stability during rolling updates
- Addition of sharding concept for Ditto internal pub/sub enabling connection of e.g. tens of thousands websocket sessions
- Background cleanup improvements in order to have less impact on DB rountrip times
- Update of third party libraries (e.g. Akka)
- Documentation of deployment via K3S
