// Creates a campaign that deploys a solution version. When a client calls the
// GetRecommendations (https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetRecommendations.html)
// and GetPersonalizedRanking (https://docs.aws.amazon.com/personalize/latest/dg/API_RS_GetPersonalizedRanking.html)
// APIs, a campaign is specified in the request. Minimum Provisioned TPS and
// Auto-Scaling A high minProvisionedTPS will increase your bill. We recommend
// starting with 1 for minProvisionedTPS (the default). Track your usage using
// Amazon CloudWatch metrics, and increase the minProvisionedTPS as necessary. A
// transaction is a single GetRecommendations or GetPersonalizedRanking call.
// Transactions per second (TPS) is the throughput and unit of billing for Amazon
// Personalize. The minimum provisioned TPS ( minProvisionedTPS ) specifies the
// baseline throughput provisioned by Amazon Personalize, and thus, the minimum
// billing charge. If your TPS increases beyond minProvisionedTPS , Amazon
// Personalize auto-scales the provisioned capacity up and down, but never below
// minProvisionedTPS . There's a short time delay while the capacity is increased
// that might cause loss of transactions. 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
// minProvisionedTPS , track your usage using Amazon CloudWatch metrics, and then
// increase the minProvisionedTPS as necessary. Status A campaign can be in one of
// the following states:
//   - CREATE PENDING > CREATE IN_PROGRESS > ACTIVE -or- CREATE FAILED
//   - DELETE PENDING > DELETE IN_PROGRESS
//
// To get the campaign status, call DescribeCampaign (https://docs.aws.amazon.com/personalize/latest/dg/API_DescribeCampaign.html)
// . Wait until the status of the campaign is ACTIVE before asking the campaign
// for recommendations. Related APIs
