Async Handler

When processing Flow at async step, you can choose a handler that will process asynchronously the Ip.

AsyncHandler

This is the default one. Ip is async processed immediately.

BatchAsyncHandler

This async process Ip as batch capability : the handler will wait for a certain amount of async messages ($batchSize) to be processed before pushing them.

DeferAsyncHandler

This async process Ip to offer defer capability : the handler will pass [$data, $defer] as entry for the job. In that case, the job can fine control the async process. $defer is a callable that embark two callbacks

• an complete callback to store result
• an async callback to go to the next async call.

Make your Async Handler

You can make your custom Ip strategy by implementing Flow\AsyncHandlerInterface
