Batching can be used to decrease the amount of communication overhead associated with the transmission and acknowledgement of small samples, in order to increase throughput. In this example we explain how to use the batching QoS setting as well as "Turbo Mode", an experimental feature that adjusts automatically the number of bytes in a batch.

Unlike Content Filter Topics, Custom Content Filters allow the use of non-relational operations between topic members, i.e. a computation involving topic members. In this example we create a Custom Content Filter takes an expression "%0 %1 x", where %0 is an integer, %1 is "divides" or "greater-than", and the "x" is the field we are comparing in the sample. The filter lets samples through if the parameter[0] divides or is greater than x, respectively.

A FlowController is the object responsible for shaping the network traffic by determining when attached asynchronous DataWriters are allowed to write data. This example shows how to create a custom flow controllers to manage an asynchronous publisher.

Usually DataReaders receive data in the order that it was sent by a DataWriter. In addition, data is presented to the DataReader as soon as the application receives the next value expected. In this example we illustrate how to control the scope of the order in which samples are presented to the subscribing application.
