// PutFunctionEventInvokeConfigRequest returns a request value for making API operation for
// AWS Lambda.
//
// Configures options for asynchronous invocation (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html)
// on a function, version, or alias. If a configuration already exists for a
// function, version, or alias, this operation overwrites it. If you exclude
// any settings, they are removed. To set one option without affecting existing
// settings for other options, use UpdateFunctionEventInvokeConfig.
//
// By default, Lambda retries an asynchronous invocation twice if the function
// returns an error. It retains events in a queue for up to six hours. When
// an event fails all processing attempts or stays in the asynchronous invocation
// queue for too long, Lambda discards it. To retain discarded events, configure
// a dead-letter queue with UpdateFunctionConfiguration.
//
// To send an invocation record to a queue, topic, function, or event bus, specify
// a destination (https://docs.aws.amazon.com/lambda/latest/dg/invocation-async.html#invocation-async-destinations).
// You can configure separate destinations for successful invocations (on-success)
// and events that fail all processing attempts (on-failure). You can configure
// destinations in addition to or instead of a dead-letter queue.
//
