AWS HealthOmics launched a feature allowing clients to pin Nextflow engine versions during workflow execution via the StartRun API's engine-settings parameter. Supported versions include 22.04 through 26.04. This capability permits customers to test workflows across engine versions without modifying source code, facilitating controlled migration especially important in regulated environments requiring pipeline validation.
By overriding manifest-specified versions, users can run production workflows on validated Nextflow versions while parallel development teams trial newer engines. This reduces unexpected behavior risks during upgrades and is available across multiple AWS HealthOmics global regions. AWS positions this as enhancing flexibility and risk management in bioinformatics workflow management.
