# GetWorkUnits


Retrieves the work units generated by the `StartQueryPlanning` operation.

## Request Syntax


```
POST /GetWorkUnits HTTP/1.1
Content-type: application/json

{
   "NextToken": "string",
   "PageSize": number,
   "QueryId": "string"
}
```

## URI Request Parameters


The request does not use any URI parameters.

## Request Body


The request accepts the following data in JSON format.

 ** [NextToken](#API_GetWorkUnits_RequestSyntax) **   <a name="lakeformation-GetWorkUnits-request-NextToken"></a>
A continuation token, if this is a continuation call.  
Type: String  
Required: No

 ** [PageSize](#API_GetWorkUnits_RequestSyntax) **   <a name="lakeformation-GetWorkUnits-request-PageSize"></a>
The size of each page to get in the AWS service call. This does not affect the number of items returned in the command's output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.  
Type: Integer  
Required: No

 ** [QueryId](#API_GetWorkUnits_RequestSyntax) **   <a name="lakeformation-GetWorkUnits-request-QueryId"></a>
The ID of the plan query operation.  
Type: String  
Length Constraints: Fixed length of 36.  
Required: Yes
