<p>Creates an empty dataset group. A dataset group is a container for Amazon Personalize resources. A dataset group can contain at most three datasets, one for each type of dataset:</p> <ul> <li> <p>Interactions</p> </li> <li> <p>Items</p> </li> <li> <p>Users</p> </li> </ul> <p> A dataset group can be a Domain dataset group, where you specify a domain and use pre-configured resources like recommenders, or a Custom dataset group, where you use custom resources, such as a solution with a solution version, that you deploy with a campaign. If you start with a Domain dataset group, you can still add custom resources such as solutions and solution versions trained with recipes for custom use cases and deployed with campaigns. </p> <p>A dataset group can be in one of the following states:</p> <ul> <li> <p>CREATE PENDING &gt; CREATE IN_PROGRESS &gt; ACTIVE -or- CREATE FAILED</p> </li> <li> <p>DELETE PENDING</p> </li> </ul> <p>To get the status of the dataset group, call <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeDatasetGroup.html">DescribeDatasetGroup</a>. If the status shows as CREATE FAILED, the response includes a <code>failureReason</code> key, which describes why the creation failed.</p> <note> <p>You must wait until the <code>status</code> of the dataset group is <code>ACTIVE</code> before adding a dataset to the group.</p> </note> <p>You can specify an Key Management Service (KMS) key to encrypt the datasets in the group. If you specify a KMS key, you must also include an Identity and Access Management (IAM) role that has permission to access the key.</p> <p class="title"> <b>APIs that require a dataset group ARN in the request</b> </p> <ul> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_CreateDataset.html">CreateDataset</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_CreateEventTracker.html">CreateEventTracker</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_CreateSolution.html">CreateSolution</a> </p> </li> </ul> <p class="title"> <b>Related APIs</b> </p> <ul> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_ListDatasetGroups.html">ListDatasetGroups</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeDatasetGroup.html">DescribeDatasetGroup</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DeleteDatasetGroup.html">DeleteDatasetGroup</a> </p> </li> </ul>
