 When it comes to handling errors from application code, i.e. from the business logic execution, it is usually up to the application to handle that.
 Because, the Kafka Streams binder does not have a way to interfere with the application code.
-However, to make things a bit easier for the application, the binder provides a convenient `DltAwareProcessor`, using which, you can dictate how you want to handle the application level errors.

+This is where `RecordRecoverableProcessor` becomes handy.
+By default, `RecordRecoverableProcessor`, will simply log the error and let the application move on.
 Let's say that you want to publish the failed record to a DLT, rather than handling it within the application.
+In that case, you must use a custom implementation of `RecordRecoverableProcessor` called `DltAwareProcessor`.
 Here is how you can do that.

 The business logic code from the original `map` call now has been moved as part of `KStream#process` method call, which takes a `ProcessorSupplier`.
 We, then, pass in the custom `DltAwareProcessor,` which is capable to publishing to a DLT.
-The constructor for `DltAwareProcessor` above takes three parameters - a `Function` that takes the input record and then the business logic operation as part of the `Function` body, the DLT topic, and finally a `DltPublishingContext`. When the `Function`'s lambda expression throws an exception, the `DltAwareProcessor` will send the input record to a DLT. The `DltPublishingContext` provides `DltAwareProcessor` the necessary publishing infrastructure beans.
