The main improvements and additions of Ditto 3.0.0 are:
- Ability to search in JSON arrays and thus also for feature definitions
- Several improvements around "metadata" in Ditto managed things
- Creation of new HTTP API for CRUD management of Ditto managed connections
- Addition of Ditto explorer UI for managing things, policies and connections
- Support for EC signed JsonWebKeys (JWKs)
- W3C WoT (Web of Things) adjustments and improvements for latest 1.1 "Candidate Recommendation" from W3C
- Make "default namespace" for creating new entities configurable
- Provide custom namespace when creating things via HTTP POST
- Make it possible to provide multiple OIDC issuer urls for a single configured openid-connect "prefix"
- Addition of a "CloudEvents" mapper for mapping CE payloads in Ditto connections
The following non-functional work is also included:
- New Ditto "thing" search index massively improving write performance; reducing the search consistency lag and improving search query performance
- Removal of former "ditto-concierge" service, moving its functionality to other Ditto services; reducing overall resource consumption and improving latency+throughput for API calls
- Creation of common way to extend Ditto via DittoExtensionPoints
- Rewrite of Ditto managed MQTT connections to use reactive-streams based client, supporting consumption applying backpressure
- Further improvements on rolling updates and other failover scenarios
- Consolidate and simplify DevOps command responses
The following notable fixes are included:
- Passwords stored in the URI of connections to no longer need to be double encoded
- Using the Normalized connection payload mapper together with enriched extra fields lead to wrongly merged things
- Adding custom Java based MessageMappers to Ditto via classpath was no longer possible
