CoreDX DDS Tips & Tricks Welcome to this month's edition of CoreDX DDS Tips & Tricks, where our engineers provide quick bits of information to help our customers. How Using or Not Using DDS Keys Impacts QoS Behavior DDS organizes samples in DataWriter and DataReader caches using instances. Data types that do not have a key result in samples belonging to the same (exactly 1) instance. Data types that define a key will result in as many instances as possible key values. Some QoS policies operate on instances, and may behave differently depending on the number of instances available. For example, a History.depth of "2" will keep up to 2 samples in each instance. With a non-keyed data type, this is a total of 2 samples. With a keyed data type, this is 2 samples for each unique key value. Other QoS policies that operate on instances include Deadline, Ownership, and Time Based Filter. Additional information on these QoS policies can be found in Chapter 12 (QoS Features) of the CoreDX DDS Programmer's Guide. CoreDX DDS Tips & Tricks are intended to be useful for engineers using CoreDX DDS. If you have any questions, please contact us.
