cdk deploy supports concurrent asset builds

Introduced 2026-03-04 · score 0.98

HOW TO USE IT

When deploying a CDK app with multiple assets, run `cdk deploy --asset-build-concurrency 4` to parallelize asset builds.

WHY THIS HELPS

When deploying a CDK app with multiple assets, build assets in parallel.

REQUIREMENTS AND LIMITATIONS

• Version: 2.1109.0
• --asset-build-concurrency 4: Sets the asset build concurrency to 4. The release note gives this invocation but does not document the option’s accepted values or default.
• Docs conflict: The current AWS `cdk deploy` reference documents `--asset-parallelism <BOOLEAN>` for parallel asset builds, not `--asset-build-concurrency`. It may describe a newer CLI version; the release note for v2.1109.0 names `--asset-build-concurrency`. https://docs.aws.amazon.com/cdk/v2/guide/ref-cli-cmd-deploy.html
