# Local Workflow Engine

## Local Workflow Engine

### Hop local workflow engine

The local run configuration runs workflows on your local environment.

This page describes the options that are specific to the local workflow engine. These options extend the general [workflow run configuration options](/data-shaper-1.21/knowing-the-data-shaper-designer/workflows/workflow-run-configurations.md).

#### Options

| Make this workflow transactional | If you enable this there will always be just one connection used per database. At the end of the workflow there will be a commit or rollback (in case of error) on all named connections at the same time. Note that child pipelines and workflows are also automatically run as a transaction. Also be aware that while you **can** commit and rollback across multiple databases that this still means that you can have a successful commit on one database and a failure on another. This is not a two-phase-commit system. |

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.primeur.com/data-shaper-1.21/knowing-the-data-shaper-designer/workflows/workflow-run-configurations/native-local-workflow-engine.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
