Measures the size of an incoming event and appends this number to the event by serializing it.
The size measure processor does not have any specific input requirements.
You can specify if the size should be in Bytes, Kilobytes (1024 Bytes) or in Megabytes (1024 Kilobytes).
The size measure processor appends the size of the event (without the field, which is getting added) as a double. The rest of the event stays the same.
