Is Business Source License 1.1 compatible with Common Development and Distribution License 1.0?

It depends.

At least one of these (`Business Source License 1.1`) is a source-available license, not OSI-approved open source. Combination terms depend on the specific clauses of the source-available license — review the upstream's FAQ and consult a lawyer before redistributing or running as a service.

About these licenses

LicenseFamilyPatent grant
Business Source License 1.1 (BUSL-1.1) source-available No (implicit at most)
Common Development and Distribution License 1.0 (CDDL-1.0) weak-copyleft Yes

Business Source License 1.1: Source-available, not OSS by OSI definition; conversion to permissive after a date.

Common Development and Distribution License 1.0: File-level copyleft, similar in spirit to MPL.
