## Description **Documentation Change Type:** - [ ] Typo/grammar fix - [ ] Clarification or minor improvement - [ ] New example or code snippet - [x] New section or topic - [ ] Major restructuring or enhancement **Affected Documentation Page(s):** - https://docs.aws.amazon.com/cdk/v2/guide/ref-cli-cmd-destroy.html ## Description of Changes Adds the new `--concurrency <NUMBER>` option to the `cdk destroy` command reference page. This option was introduced in [aws/aws-cdk-cli#1221](aws/aws-cdk-cli#1221). Also adds a usage example showing concurrent stack deletion. ## Motivation and Context The `--concurrency` flag for `cdk destroy` has shipped in the CDK CLI but is not yet documented. The option mirrors the existing `cdk deploy --concurrency` behavior, allowing users to destroy multiple stacks in parallel while respecting dependency order. ## How Has This Been Validated? - Verified formatting is consistent with the existing `--concurrency` option on the `cdk deploy` reference page - Confirmed all facts against the source PR ([aws/aws-cdk-cli#1221](aws/aws-cdk-cli#1221)) ## Checklist - [x] My changes follow the [AsciiDoc syntax](./CONTRIBUTING.md#asciidoc-syntax-reference) guidelines - [x] I have previewed my changes using GitHub's preview or a local AsciiDoc renderer - [x] My changes maintain consistent formatting with the rest of the documentation - [x] I have checked that all links work correctly ## Additional Information The option entry and example were modeled directly on the existing `--concurrency` documentation for `cdk deploy` to ensure consistency. --------- Co-authored-by: Momo Kornher <mail@moritzkornher.de>

Fixes #752
Description
Add
--concurrencyflag tocdk destroy, mirroring the existingcdk deploy --concurrencybehavior. When set to a value greater than 1, multiple stacks are destroyed in parallel while respecting dependency order (reversed from deploy).Uses
WorkGraphwith reversed dependency edges to orchestrate parallel destruction. A newWorkGraph.processStacks()method provides a stack-only execution path, and the graph construction logic lives in its ownbuild-destroy-work-graphmodule.Checklist
