The base controller in client-go provides the *NewIndexerInformer* function to create Informer and Indexer.
In your code you can either [directly invoke this function](https://github.com/kubernetes/client-go/blob/master/examples/workqueue/main.go#L174) or [use factory methods for creating an informer.](https://github.com/kubernetes/sample-controller/blob/master/main.go#L61)

* Resource Event Handlers: These are the callback functions which will be called by
the Informer when it wants to deliver an object to your controller. The typical
pattern to write these functions is to obtain the dispatched object’s key
and enqueue that key in a work queue for further processing.

* Work queue: This is the queue that you create in your controller code to decouple
delivery of an object from its processing. Resource event handler functions are written
to extract the delivered object’s key and add that to the work queue.

from the work queue. There can be one or more other functions that do the actual processing.
* Process Item: This is the function that you create in your code which processes items

These functions will typically use the [Indexer reference](https://github.com/kubernetes/client-go/blob/master/examples/workqueue/main.go#L73), or a Listing wrapper to retrieve the object corresponding to the key.
