# transforms.api.LightweightContext

## *class* transforms.api.LightweightContext {#transforms.api.LightweightContext}

A context object that can optionally be injected into the compute function of a lightweight transform.

Can be accessed by adding a `ctx` argument to the compute function as shown below:

```python
>>> @transform.using(...)
... def compute(ctx, ...):
...     ...
```

Equivalent to [`transforms.api.TransformContext`](../api-transformcontext/index.md#transforms.api.TransformContext) for single node compute.

### abort\_job() {#transforms.api.LightweightContext.abort\_job}

### *property* auth\_header {#transforms.api.LightweightContext.auth\_header}

### *property* is\_incremental {#transforms.api.LightweightContext.is\_incremental}
