==== AWS Request Handlers
The adapter has a couple of generic request handlers that you can use. The most generic is (and the one we used in the Getting Started section)
is `org.springframework.cloud.function.adapter.aws.FunctionInvoke` which is the implementation of AWS's `RequestStreamHandler`.
is `org.springframework.cloud.function.adapter.aws.FunctionInvoker` which is the implementation of AWS's `RequestStreamHandler`.
User doesn't need to do anything other then specify it as 'handler' on AWS dashborad when deploying function.
It will handle most of the case including Kinesis, streaming etc. .
The most generic is
`SpringBootStreamHandler`, which uses a Jackson `ObjectMapper` provided by Spring Boot to serialize and deserialize the objects
in the function. There is also a `SpringBootRequestHandler` which you can extend, and provide the input and output types as type
parameters (enabling AWS to inspect the class and do the JSON conversions itself).
If your app has more than one `@Bean` of type `Function` etc. then you can choose the one to use by configuring `function.name`
(e.g. as `FUNCTION_NAME` environment variable in AWS). The functions are extracted from the Spring Cloud `FunctionCatalog`
(searching first for `Function` then `Consumer` and finally `Supplier`).
If your app has more than one `@Bean` of type `Function` etc. then you can choose the one to use by configuring `spring.cloud.function.definition`
property or environment variable. The functions are extracted from the Spring Cloud `FunctionCatalog`. In the event you don't specify `spring.cloud.function.definition`
the framework will attempt to find a default following the search order where it searches first for `Function` then `Consumer` and finally `Supplier`).
