Spring Boot 3.x support

SCDF Spring Boot 3.x Support

Custom Applications

Able to launch custom SB3 SCSt apps.

Note	SCT/B app work on Postgres but fail on MariaDB due to use of sequences.

Micrometer

Able to use existing Micrometer metrics and tags.

Spring Cloud Sleuth

SCS does not work in SB3 (not auto-configured).

Observations API

Able to use Observations API on top of any existing legacy MM metrics.

OOTB Applications

SB3 support not yet available in stream-applications (neither SCSt or SCTb). When it is available we still need to figure SCDF plan to launch 2.x and 3.x apps. Changes will be required likely in SCDF and SA.

Affected Areas

Spring Cloud Sleuth

SCS does not work in SB3 (not auto-configured).

• SCS removed from SC BOM → SCS deps MUST be removed from apps pom.xml

• SCS props SHOULD be removed from the app props

Native Support
