## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_redshift as redshift } from 'aws-cdk-lib';
const cfnUsageLimitProps: redshift.CfnUsageLimitProps = {
  amount: 123,
  clusterIdentifier: 'clusterIdentifier',
  featureType: 'featureType',
  limitType: 'limitType',

  // the properties below are optional
  breachAction: 'breachAction',
  period: 'period',
  tags: [{
    key: 'key',
    value: 'value',
  }],
};
```

## Properties

- `amount`: number (required) — The limit amount.

  If time-based, this amount is in minutes. If data-based, this amount is in terabytes (TB). The value must be a positive number.

- `breachAction`: string — The action that Amazon Redshift takes when the limit is reached.

  The default is log.

- `clusterIdentifier`: string (required) — The identifier of the cluster that you want to limit usage.

- `featureType`: string (required) — The Amazon Redshift feature that you want to limit.

- `limitType`: string (required) — The type of limit.

  Depending on the feature type, this can be based on a time duration or data size. If FeatureType is spectrum, then LimitType must be data-scanned. If FeatureType is concurrency-scaling, then LimitType must be time. If FeatureType is cross-region-datasharing, then LimitType must be data-scanned.

- `period`: string — The time period that the amount applies to.

  A weekly period begins on Sunday. The default is monthly.

- `tags`: [CfnTag](/cdk/api/v2/docs/aws-cdk-lib.CfnTag.html)[] — A list of tag instances.
