Topic Aliasing
Topic names form part of each Message header, so the smaller the Topic name the better. However, when hierarchic Topics are in use it may be difficult to keep Topic names short.
Topic aliasing is a mechanism for automatically using short Topic names in all Messages. The Topic Aliasing feature is optional.
The use of Topic aliases can save a significant amount of network traffic, however there is a trade off of a small processing cost which can reduce the Message throughput.
When turned on, the creation of Topic Load Messages causes short Topic aliases to be generated for all Topic names greater than 4 characters in length. Delta messages will then only contain the Topic alias thus saving space in each Message sent.
