/**
* Client for accessing Amazon CloudWatch Events asynchronously. Each asynchronous method will return a Java Future
* object representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
* notification when an asynchronous operation completes.
*
*
* Amazon CloudWatch Events helps you to respond to state changes in your AWS resources. When your resources change
* state they automatically send events into an event stream. You can create rules that match selected events in the
* stream and route them to targets to take action. You can also use rules to take action on a pre-determined schedule.
* For example, you can configure rules to:
*
*
* - Automatically invoke an AWS Lambda function to update DNS entries when an event notifies you that Amazon EC2
* instance enters the running state.
* - Direct specific API records from CloudTrail to an Amazon Kinesis stream for detailed analysis of potential
* security or availability risks.
* - Periodically invoke a built-in target to create a snapshot of an Amazon EBS volume.
*
*
* For more information about Amazon CloudWatch Events features, see the Amazon CloudWatch Developer Guide.
