Functional Categories

These categories help you to discover which QoS may be relevant or related to a desired functionality or feature. For example, if you are interested in Sending Large Data, then looking at any QoS in that category will be helpful. More...

Modules
	Application Acknowledgement
	This page lists all QoS related to application acknowledgement.
	Application-Defined Metadata
	This page lists QoS fields that can be used to send application-specific data during participant and endpoint discovery.
	Application Startup
	Use these QoS fields to configure entity creation and application startup settings.
	Batching
	Use these QoS fields to configure the batching feature.
	Concurrency
	Use these QoS fields to configure threads and concurrency settings in RTI Connext.
	Content Filtering
	Use these QoS fields if you are using content filtering on your data.
	Data Availability
	Use these QoS fields to configure how much data, which data, and when that data is available to an application.
	Debuggability
	Use these QoS to configure logging and observability capabilities to help debug RTI Connext applications.
	Discovery
	Use these QoS fields to configure how applications discover each other.
	Discovery Isolation
	Use these QoS fields to isolate applications from each other.
	Durability
	Use these QoS fields to configure how much and how long data remains retrievable in the system.
	Flow Control
	Use these QoS fields to configure features which help to control the rate at which data is sent, preventing network congestion.
	Fragmentation
	QoS related to DDS-level data fragmentation.
	Instance Lifecycle
	QoS that control the lifecycle of instances.
	Sending Large Data
	Use these QoS fields to optimize the process of sending large data.
	Liveliness
	Use these QoS fields to manage the liveliness of participants and endpoints, ensuring active communication and timely updates of the system state.
	Logging
	Use these QoS fields to configure the RTI Connext logging infrastructure.
	Middleware Memory Management
	Use these QoS fields to configure the memory usage of the middleware, including various initial and max limits.
	QoS Profile Management
	Use these QoS fields to configure how QoS profiles are loaded and which ones should be used when entities are created.
	Reliability QoS
	Reliability related QoS.
	Sample Memory Management QoS
	Use these QoS fields to configure how Connext manages memory related to the samples that are stored and managed by the DataReader and DataWriter queues.
	Sample Ordering
	Use these QoS fields to configure how samples are ordered when stored and accessed by a DataReader.
	Security
	Use these QoS fields to enable and configure some security-related capabilities in RTI Connext.
	Throughput
	Use these QoS fields to configure features which may be helpful to increase throughput.
	Transports
	Use these QoS fields to configure aspects of the transports (udp, shared memory, etc.) used for communication.
	Topic Queries
	Use these QoS fields to configure the topic query feature.
	Type System
	Use these QoS fields to configure aspects of the type system.
