// A flywheel is an Amazon Web Services resource that orchestrates the ongoing
// training of a model for custom classification or custom entity recognition. You
// can create a flywheel to start with an existing trained model, or Comprehend can
// create and train a new model. When you create the flywheel, Comprehend creates a
// data lake in your account. The data lake holds the training data and test data
// for all versions of the model. To use a flywheel with an existing trained model,
// you specify the active model version. Comprehend copies the model's training
// data and test data into the flywheel's data lake. To use the flywheel with a new
// model, you need to provide a dataset for training data (and optional test data)
// when you create the flywheel. For more information about flywheels, see
// Flywheel overview (https://docs.aws.amazon.com/comprehend/latest/dg/flywheels-about.html)
// in the Amazon Comprehend Developer Guide.
