## Property details

### IExecutionConfig.dataSamplingPercentage

Data sampling is only available in Tiger for specific databases

**Signature:**

```typescript
dataSamplingPercentage?: number;
```

### IExecutionConfig.measureDefinitionOverrides

> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

(EXPERIMENTAL) Override definitions of catalog metrics for this execution request.

**Signature:**

```typescript
measureDefinitionOverrides?: IMeasureDefinitionOverride[];
```

#### Remarks

Allows substituting a catalog metric's MAQL definition without modifying the stored definition. This is useful for ad-hoc metric customization at execution time.

### IExecutionConfig.parameterValues

> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

(EXPERIMENTAL) Values of workspace parameters for this execution request.

**Signature:**

```typescript
parameterValues?: IInsightParameterValue[];
```

#### Remarks

Each entry substitutes the default value of the referenced parameter without modifying the stored parameter definition.

### IExecutionConfig.timestamp

Execution timestamp as ISO string

**Signature:**

```typescript
timestamp?: string;
```

#### Remarks

This may alter the data for computation when using date filters (e.g. last year)

### IExecutionConfig.timezone

> **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md).
> 

Timezone in which the execution should be evaluated.

**Signature:**

```typescript
timezone?: string;
```

#### Remarks

Must be a concrete IANA time zone identifier (e.g. "Europe/Prague"). Never pass the browser-detected sentinel value here; resolve it to a concrete identifier first.
