// CreateCampaignRequest returns a request value for making API operation for
// Amazon Personalize.
//
// Creates a campaign by deploying 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 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,
// to maintain a 70% utilization. There's a short time delay while the capacity
// is increased that might cause loss of transactions. It's recommended to start
// 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.
//
// Wait until the status of the campaign is ACTIVE before asking the campaign
// for recommendations.
//
// Related APIs
