<p>Creates a campaign that deploys a solution version. When a client calls the <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html">GetRecommendations</a> and <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetPersonalizedRanking.html">GetPersonalizedRanking</a> APIs, a campaign is specified in the request.</p> <p> <b>Minimum Provisioned TPS and Auto-Scaling</b> </p> <p>A transaction is a single <code>GetRecommendations</code> or <code>GetPersonalizedRanking</code> call. Transactions per second (TPS) is the throughput and unit of billing for Amazon Personalize. The minimum provisioned TPS (<code>minProvisionedTPS</code>) specifies the baseline throughput provisioned by Amazon Personalize, and thus, the minimum billing charge. </p> <p> If your TPS increases beyond <code>minProvisionedTPS</code>, Amazon Personalize auto-scales the provisioned capacity up and down, but never below <code>minProvisionedTPS</code>. There's a short time delay while the capacity is increased that might cause loss of transactions.</p> <p>The actual TPS used is calculated as the average requests/second within a 5-minute window. You pay for maximum of either the minimum provisioned TPS or the actual TPS. We recommend starting with a low <code>minProvisionedTPS</code>, track your usage using Amazon CloudWatch metrics, and then increase the <code>minProvisionedTPS</code> as necessary.</p> <p> <b>Status</b> </p> <p>A campaign 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 &gt; DELETE IN_PROGRESS</p> </li> </ul> <p>To get the campaign status, call <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeCampaign.html">DescribeCampaign</a>.</p> <note> <p>Wait until the <code>status</code> of the campaign is <code>ACTIVE</code> before asking the campaign for recommendations.</p> </note> <p class="title"> <b>Related APIs</b> </p> <ul> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_ListCampaigns.html">ListCampaigns</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeCampaign.html">DescribeCampaign</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_UpdateCampaign.html">UpdateCampaign</a> </p> </li> <li> <p> <a href="https://docs.aws.amazon.com/personalize/latest/dg/API_DeleteCampaign.html">DeleteCampaign</a> </p> </li> </ul>
