Detailed Description

<<extension>> QoS libraries, profiles, and snippets that are automatically built into RTI Connext.

The built-in profiles can be accessed in QoS XML configuration files and by using any of the APIs that accept library and profiles names by using the constants or string versions as documented on this page.

The built-in profiles are provided as a way to quickly and easily configure RTI Connext applications with a set of QoS values aimed at achieving a specific behavior.

There are three built-in QoS libraries:

BuiltinQosLib: A library containing built-in QoS Profiles.

BuiltinQosLibExp: A library containing experimental QoS Profiles. Experimental QoS Profiles are new QoS Profiles that have been tested internally but have not gone through an extensive validation period. Therefore, some of the settings may change in future releases based on customer and internal feedback. After validation, experimental QoS Profiles will be moved into the non-experimental library.

BuiltinQosSnippetLib: A library containing QoS Snippets that are ready to use as elements for the QoS Profile composition pattern. For further information about this pattern visit the following article: https://community.rti.com/best-practices/qos-profile-inheritance-and-composition-guidance

There are three types of profiles:

Baseline.X.X.X: These profiles represent the QoS defaults for /ndds version X.X.X. To access the defaults for the latest RTI Connext version, use the BuiltinQosLib::Baseline profile.
Generic.X: These profiles allow you to easily configure different features and communication use-cases with RTI Connext. For example, there is a Generic.StrictReliable profile for use when your application has a requirement for no data loss.
Pattern.X: These profiles inherit from the Generic.X profiles and allow you to configure various domain-specific communication use cases. For example, there is a Pattern.Alarm profile that can be used to manage the generation and consumption of alarm events.

There are several types of QoS Snippets. These are the current QoS Snippets available:

Optimization.X: these QoS Snippets optimize one or more parameters related to the X QoS Policy or a specific use-case.
QosPolicy.X.Y: these QoS Snippets set a specific QoS Policy X to the value Y.
Feature.X: these QoS Snippets set all the needed QoS values to enable/modify a specific feature.
Transport.X: these QoS Snippets set a specific transport defined by X. This transport may have specific scenarios that are also specified in the name.
Compatibility.X: these QoS Snippets change the specific QoS policies to ensure compatibility with specific products or versions specified by X.

These QoS Profiles can be used as base profiles in XML configuration, then QoS Snippets can modify specific aspects of this base QoS Profile, and finally files and values can be modified to fit a specific system's needs. For example:

<qos_profile name="MyProfile" base_name="BuiltinQosLib::Generic.Common">
    <domain_participant_qos base_name="BuiltinQosLib::Generic.Monitoring.Common">
      <base_name>
        <element>BuiltinQosSnippetLib::Feature.Monitoring.Enable</element>
      </base_name>
      <!-- Override and add values -->
    </domain_participant_qos>
 </qos_profile>          

The QoS Profiles can also be used in any APIs that call for a QoS library and profile name, for example, the create_*_with_profile() APIs. To create a com.rti.dds.publication.DataWriter configured to send large data:

writer = DDS_DomainParticipant_create_datawriter_with_profile(
                  participant, topic, 
                  com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB, 
                  com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA_FAST_FLOW, 
                  NULL, com.rti.dds.infrastructure.StatusKind.STATUS_MASK_NONE); 

All the built-in QoS Profiles and QoS Snippets are documented in the BaselineRoot.documentationONLY.xml and BuiltinProfiles.documentationONLY.xml files that are included in the NDDSHOME/xml directory of the RTI Connext installation.

BaselineRoot.documentationONLY.xml contains the root baseline QoS profile that corresponds to the default values of RTI Connext 5.0.0.

BuiltinProfiles.documentationONLY.xml contains the rest of the built-in Qos Profiles and QoS Snippets.

String-version: "Generic.ConnextMicroCompatibility"

◆ PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_9

final String PROFILE_GENERIC_CONNEXT_MICRO_COMPATIBILITY_2_4_9

static

Sets the values necessary to communicate with RTI Connext Micro versions 2.4.4 through at least 2.4.9.

At the time of the release of RTI Connext 5.3.0 it was not necessary to set any QoS values in order to interoperate with RTI Connext Micro. This applies to RTI Connext Micro versions 2.4.4 and later. The most recent version of RTI Connext Micro at the time of release of RTI Connext 5.3.0 was 2.4.9. There is no guarantee that this profile will interoperate with versions of RTI Connext Micro after 2.4.9.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB

String-version: "Generic.ConnextMicroCompatibility.2.4.9"

RTI Connext Micro versions 2.4.3 and earlier only supported the com.rti.dds.infrastructure.LivelinessQosPolicyKind.LivelinessQosPolicyKind.MANUAL_BY_TOPIC_LIVELINESS_QOS LivelinessQos kind. In order to be compatible with these versions of RTI Connext Micro, the com.rti.dds.subscription.DataReader and com.rti.dds.publication.DataWriter must have their Liveliness kind changed to this value because the default kind in RTI Connext is com.rti.dds.infrastructure.LivelinessQosPolicyKind.LivelinessQosPolicyKind.AUTOMATIC_LIVELINESS_QOS.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB

String-version: "Generic.510TransportCompatibility"

◆ PROFILE_GENERIC_SECURITY

final String PROFILE_GENERIC_SECURITY

static

Loads the DDS Secure builtin plugins.

Generic Base Participant Profile that enables the builtin DDS Security Plugins.

Use of this QoS Profile is deprecated. It is included for backwards compatibility.

Instead of using the (deprecated) "BuiltinQosLib::Generic.Security", apply the QoS Snippet "BuiltinQosSnippetLib::Feature.Security.Enable" via composition. For example:

<qos_profile name="MyProfile">
     <base_name>
         <element>BuiltinQosSnippetLib::Feature.Security.Enable</element>
     </base_name>
 </qos_profile>

Legacy applications may use this QoS Profile via inheritance. To do this, create a derived QoS Profile that inherits from this one. For example:

<qos_profile name="MyProfile" base_name="BuiltinQosLib::Generic.StrictReliable">
     <domain_participant_qos base_name="BuiltinQosLib::Generic.Security">
 </qos_profile>

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB

String-version: "Generic.Security"

◆ BUILTIN_QOS_LIB_EXP

final String BUILTIN_QOS_LIB_EXP

static

A library of experimental QoS profiles.

Experimental profiles are new profiles that have been tested internally but have not gone through an extensive validation period. Therefore some of the settings may change in future releases based on customer and internal feedback. After validation, experimental profiles will be moved into the non-experimental library.

QoS Profiles in this library are deprecated. They have been moved to "BuiltinQosLib". You should use the QoS Profiles from "BuiltinQosLib" instead of the ones in "BuiltinQosLibExp". The experimental profiles are still defined here to avoid backward compatibility issues.

String-version: "BuiltinQosLibExp"

◆ PROFILE_GENERIC_STRICT_RELIABLE

final String PROFILE_GENERIC_STRICT_RELIABLE

static

Enables strict reliability.

Configures communication to be "strict reliable" where every sample is reliably delivered.

Combines the use of the com.rti.dds.infrastructure.ReliabilityQosPolicyKind.RELIABLE_RELIABILITY_QOS for com.rti.dds.infrastructure.ReliabilityQosPolicy with a com.rti.dds.infrastructure.HistoryQosPolicyKind.HistoryQosPolicyKind.KEEP_ALL_HISTORY_QOS for the com.rti.dds.infrastructure.HistoryQosPolicyKind.

This QoS Profile also optimizes the reliability protocol setting for this configuration.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable"

◆ PROFILE_GENERIC_KEEP_LAST_RELIABLE

final String PROFILE_GENERIC_KEEP_LAST_RELIABLE

static

Enables keep-last reliability.

Like the Generic.StrictReliable profile, this profile ensures in-order delivery of samples. However, new data can overwrite data that has not yet been acknowledged by the reader, therefore causing possible sample loss.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.KeepLastReliable"

◆ PROFILE_GENERIC_BEST_EFFORT

final String PROFILE_GENERIC_BEST_EFFORT

static

Enables best-effort reliability kind.

This profile enables best-effort communication. No effort or resources are spent to track whether or not sent samples are received. Minimal resources are used. This is the most deterministic method of sending data since there is no indeterministic delay that can be introduced by resending data. Data samples may be lost. This setting is good for periodic data.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.BestEffort"

◆ PROFILE_GENERIC_STRICT_RELIABLE_HIGH_THROUGHPUT

final String PROFILE_GENERIC_STRICT_RELIABLE_HIGH_THROUGHPUT

static

A profile that can be used to achieve high throughput.

This QoS Profile extends the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE QoS Profile to perform additional, fine-grained performance tuning specific to applications that send continuously streaming data. The parameters specified here add to and/or override the parameters specified in the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE QoS Profile..

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable.HighThroughput"

◆ PROFILE_GENERIC_STRICT_RELIABLE_LOW_LATENCY

final String PROFILE_GENERIC_STRICT_RELIABLE_LOW_LATENCY

static

A profile that can be used to achieve low latency.

This QoS Profile extends the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE QoS Profile to perform additional, fine-grained performance tuning specific to applications that send continuously streaming data. The parameters specified here add to and/or override the parameters specified in the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE QoS Profile.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.StrictReliable.LowLatency"

◆ PROFILE_GENERIC_PARTICIPANT_LARGE_DATA

final String PROFILE_GENERIC_PARTICIPANT_LARGE_DATA

static

A common Participant base profile to facilitate sending large data.

This is a common Participant base QoS Profile that configures 3 different flow controllers: 838, 209, and 52 Mbps that can each be used to throttle application data flow at different rates.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Generic.Participant.LargeData"

◆ PROFILE_GENERIC_PARTICIPANT_LARGE_DATA_MONITORING

final String PROFILE_GENERIC_PARTICIPANT_LARGE_DATA_MONITORING

static

Configures Participants for large data and monitoring.

This is a common base Participant QoS Profile to configure Participants to both handle large data and use RTI Monitoring Library.

This QoS Profile is deprecated. It is included for backwards compatibility.

It is recommended that instead of inheriting from this QoS Profile, new applications apply the following QoS Snippets to their application-specific QoS Profiles:

Enable Monitoring

com.rti.dds.infrastructure.BuiltinQosProfiles.SNIPPET_FEATURE_MONITORING_ENABLE

Enable Large Data + optimizations

String-version: "Generic.Participant.LargeData.Monitoring"

See also: com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_PARTICIPANT_LARGE_DATA; com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_MONITORING_COMMON

◆ PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA

final String PROFILE_GENERIC_STRICT_RELIABLE_LARGE_DATA

static

Configures endpoints for sending large data with strict reliability.

This QoS Profile extends the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_PARTICIPANT_LARGE_DATA QoS Profile to handle sending large samples. This QoS Profile optimizes memory usage per sample within RTI Connext, but it does not do any flow control. You can use this QoS Profile directly, which enables asynchronous publication with the default flow controller (i.e. no flow control) or you can use one of the three QoS Profiles below (Generic.StrictReliable.LargeData.*Flow), which uses this QoS Profile as a common base QoS Profile. Each of these three QoS Profiles uses one of the three flow controllers defined in com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_PARTICIPANT_LARGE_DATA in order to throttle application data flow.

◆ PROFILE_PATTERN_PERIODIC_DATA

final String PROFILE_PATTERN_PERIODIC_DATA

static

Used for applications that expect periodic data.

This QoS Profile is intended to be used for applications that expect periodic data such as sensor data. The deadline that is set in this profile can be used to detect when DataWriters are not publishing data with the expected periodicity.

String-version: "Pattern.PeriodicData"

◆ PROFILE_PATTERN_STREAMING

final String PROFILE_PATTERN_STREAMING

static

Used for applications that stream data.

The data sent in streaming applications is commonly periodic. Therefore this profile simply inherits from the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_PERIODIC_DATA profile. Note: With this QoS Profile, the application may lose data, which may be acceptable in use cases such as video conferencing.

String-version: "Pattern.Streaming"

◆ PROFILE_PATTERN_RELIABLE_STREAMING

final String PROFILE_PATTERN_RELIABLE_STREAMING

static

Used for applications that stream data and require reliable communication.

Sometimes streaming applications require reliable communication while still tolerating some data loss. In this case, we inherit from the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_KEEP_LAST_RELIABLE QoS Profile and the following QoS Snippets:

This QoS Snippet also increases the com.rti.dds.infrastructure.HistoryQosPolicy.depth to reduce the probability of losing samples.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Pattern.ReliableStreaming"

◆ PROFILE_PATTERN_EVENT

final String PROFILE_PATTERN_EVENT

static

Used for applications that handle events.

This QoS Profile can be used by applications in which samples represent events such as button pushes or alerts. When events are triggered, the system should almost always do something, meaning that you don't want the system to lose the event. This means that the system requires strictly reliable communication. To enable it, use the following QoS Snippets:

Since events and alerts are critical and non-periodic data, it is important to detect situations in which communication between a com.rti.dds.publication.DataWriter and com.rti.dds.subscription.DataReader is broken. This is why this profile sets the com.rti.dds.infrastructure.LivelinessQosPolicy. If the com.rti.dds.publication.DataWriter does not assert its liveliness in a timely manner, the com.rti.dds.subscription.DataReader will report 'loss of liveliness' to the application.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Pattern.Event"

◆ PROFILE_PATTERN_ALARM_EVENT

final String PROFILE_PATTERN_ALARM_EVENT

static

Used for applications that handle alarm events.

An alarm is a type of event; therefore this profile simply inherits from com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_EVENT.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Pattern.AlarmEvent"

◆ PROFILE_PATTERN_STATUS

final String PROFILE_PATTERN_STATUS

static

Used for applications whose samples represent statuses.

This QoS Profile can be used by applications in which samples represent state variables whose values remain valid as long as they don't explicitly change. State variables typically do not change periodically. State variables and their values should also be available to applications that appear after the value originally changed because it is unreasonable to have to wait until the next change of state, which may be indeterminate.

Whether to use this QoS Profile or com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_PERIODIC_DATA can often be an application choice. For example, if a DataWriter is publishing temperature sensor data, it could use the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_PERIODIC_DATA QoS Profile and publish the data at a fixed rate or it could use the com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_STATUS QoS Profile and only publish the temperature when it changes more than 1 degree.

String-version: "Pattern.Status"

◆ PROFILE_PATTERN_ALARM_STATUS

final String PROFILE_PATTERN_ALARM_STATUS

static

Used for applications in which samples represent alarm statuses.

An alarm status is a type of status; therefore this QoS Profile simply inherits from com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_PATTERN_STATUS.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Pattern.AlarmStatus"

◆ PROFILE_PATTERN_LAST_VALUE_CACHE

final String PROFILE_PATTERN_LAST_VALUE_CACHE

static

Used for applications that only need the last published value.

With this QoS Profile, a com.rti.dds.publication.DataWriter will keep in its queue the last value that was published for each sample instance. Late-joining DataReaders will get that value when they join the system. This QoS Profile inherits from com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_KEEP_LAST_RELIABLE_TRANSIENT_LOCAL because the use case requires delivery to late-joiners.

In Library: com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB and com.rti.dds.infrastructure.BuiltinQosProfiles.BUILTIN_QOS_LIB_EXP

String-version: "Pattern.LastValueCache"

This QoS Snippet defines parameters common to a set of "alternative" QoS Snippets that configure the reliability protocol.

Modified QoS Parameters:

This QoS Snippet configures the reliability protocol parameters for more aggressive (faster) heartbeats so that sample loss is detected and repaired faster.

This QoS Snippet also sets the com.rti.dds.infrastructure.RtpsReliableWriterProtocol_t.max_heartbeat_retries, which works in combination with the heartbeat rate to determine when the com.rti.dds.publication.DataWriter considers a com.rti.dds.subscription.DataReader non-responsive. This QoS Snippet configures the com.rti.dds.infrastructure.DataWriterProtocolQosPolicy.rtps_reliable_writer parameters so that the com.rti.dds.publication.DataWriter considers the com.rti.dds.subscription.DataReader to be "inactive" after 500 unresponded heartbeats.

final String SNIPPET_OPTIMIZATION_RELIABILITY_PROTOCOL_HIGH_RATE

static

QoS Snippet that configures the reliability protocol for sending data at a high rate.

The QoS Snippets starting with "Optimization.ReliabilityProtocol." provide alternative configurations of the same QoS Policies. Choose just one QoS Snippet of the alternatives when defining a new QoS Profile or QoS Snippet.

This QoS Snippet optimizes the com.rti.dds.publication.DataWriter reliable protocol parameters for a reliable com.rti.dds.publication.DataWriter that is writing messages at high rates, especially in situations where throughput is favored over latency.

Modified QoS Parameters:

This QoS Snippet sets a fast rate of heartbeats so that errors are detected and repaired more swiftly.

Note that to get the highest thoughout you may need to apply additional changes to the final QoS Profile. See the QoS Profile com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE_HIGH_THROUGHPUT for further information.

final String SNIPPET_OPTIMIZATION_RELIABILITY_PROTOCOL_LARGE_DATA

static

QoS Snippet that configures the reliability protocol for large data.

The QoS Snippets starting with "Optimization.ReliabilityProtocol." provide alternative configurations of the same QoS Policies. Choose just one QoS Snippet of the alternatives when defining a new QoS Profile or QoS Snippet.

Modifies the Reliable Protocol parameters and Resource Limits to work with Large Data.

Modified QoS Parameters:

Note that to send large data you need to apply additional changes that configure the data caches, asynchronous writing, transport buffers, etc. See, for example, com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_KEEP_LAST_RELIABLE_LARGE_DATA, and derivatives for fully functional Large Data QoS Profiles.

final String SNIPPET_OPTIMIZATION_DATACACHE_LARGE_DATA_DYNAMICMEMALLOC

static

Configures the DataWriter and DataReader caches to use dynamic memory allocation for Large Data samples.

Modified QoS Parameters:

com.rti.dds.publication.DataWriterQos => com.rti.dds.infrastructure.ResourceLimitsQosPolicy
com.rti.dds.publication.DataWriterQos => com.rti.dds.infrastructure.PropertyQosPolicy named "dds.data_writer.history.memory_manager.*"

This configuration is needed to handle data that contains unbounded sequences or strings. This QoS Snippet is also recommended if samples can have very different sizes and the bigger samples can be very large.

If dynamic memory allocation is not used for the larger samples, then all samples are allocated to their maximum size which can consume a lot of resources.

◆ SNIPPET_QOS_POLICY_RELIABILITY_RELIABLE

final String SNIPPET_QOS_POLICY_RELIABILITY_RELIABLE

static

QoS Snippet that sets RELIABILITY QoS to RELIABLE.

This also configures a blocking time in case the com.rti.dds.publication.DataWriter writes faster than the DataReaders can accommodate.

Modified QoS Parameters:

Note that by itself enabling reliability does not ensure that every sample written is delivered to the DataReaders. This is because the com.rti.dds.publication.DataWriter and/or com.rti.dds.subscription.DataReader can be configured to override samples in its cache based on the configuration of the com.rti.dds.infrastructure.HistoryQosPolicy QoS policy.

To ensure delivery of every sample (at the expense of potentially blocking the com.rti.dds.publication.DataWriter), use the QoS Profile com.rti.dds.infrastructure.BuiltinQosProfiles.PROFILE_GENERIC_STRICT_RELIABLE or one of the derived QoS Profiles.

◆ SNIPPET_QOS_POLICY_RELIABILITY_BEST_EFFORT

final String SNIPPET_QOS_POLICY_RELIABILITY_BEST_EFFORT

static

QoS Snippet that sets RELIABILITY QoS to BEST_EFFORT.

Modified QoS Parameters:

With best-effort, there are no resources spent to confirm delivery of samples nor repairs of any samples that may be lost.

Best-effort communication reduces jitter; therefore, the delay between sending data and receiving it is more deterministic for the samples that are actually received. Best-effort is good for periodic data where it may be better to get the next value than to wait for the previous one to be repaired.

static

QoS Snippet that sets DURABILITY QosPolicy to TRANSIENT_LOCAL kind.

Modified QoS Parameters:

DataWriters will store and send previously published DDS samples for delivery to newly discovered DataReaders as long as the com.rti.dds.publication.DataWriter still exists. For this setting to be effective, you must also set the com.rti.dds.infrastructure.ReliabilityQosPolicyKind to com.rti.dds.infrastructure.ReliabilityQosPolicyKind.RELIABLE_RELIABILITY_QOS (not Best Effort). Which particular DDS samples are kept depends on other QoS settings such as com.rti.dds.infrastructure.HistoryQosPolicy and com.rti.dds.infrastructure.ResourceLimitsQosPolicy.

static

QoS Snippet that sets DURABILITY QosPolicy to TRANSIENT kind.

Modified QoS Parameters:

RTI Connext will store previously published DDS samples in memory using Persistence Service, which will send the stored data to newly discovered DataReaders. Which particular DDS samples are kept and sent by Persistence Service depends on the com.rti.dds.infrastructure.HistoryQosPolicy and com.rti.dds.infrastructure.ResourceLimitsQosPolicy of the Persistence Service DataWriters. These QosPolicies can be configured in the Persistence Service configuration file or through the com.rti.dds.infrastructure.DurabilityQosPolicyKind of the DataWriters configured with com.rti.dds.infrastructure.DurabilityQosPolicyKind.DurabilityQosPolicyKind.TRANSIENT_DURABILITY_QOS.

◆ SNIPPET_FEATURE_AUTO_TUNING_ENABLE

final String SNIPPET_FEATURE_AUTO_TUNING_ENABLE

static

QoS Snippet that enables auto_throttle and turbo_mode to true.

Sets the com.rti.dds.domain.DomainParticipantQos properties to enable auto_throttle and turbo_mode to true.

Modified QoS Parameters:

com.rti.dds.domain.DomainParticipantQos => com.rti.dds.infrastructure.PropertyQosPolicy named "dds.domain_participant.auto_throttle"
com.rti.dds.publication.DataWriterQos => com.rti.dds.infrastructure.PropertyQosPolicy named "dds.data_writer.auto_throttle.enable"
com.rti.dds.publication.DataWriterQos => com.rti.dds.infrastructure.PropertyQosPolicy named "dds.data_writer.enable_turbo_mode"

The domain_participant.auto_throttle configures the com.rti.dds.domain.DomainParticipant to gather internal measurements (during com.rti.dds.domain.DomainParticipant creation) that are required for the Auto Throttle feature. This allows DataWriters belonging to this com.rti.dds.domain.DomainParticipant to use the Auto Throttle feature.

The turbo_mode adjusts the batch max_data_bytes based on how frequently the com.rti.dds.publication.DataWriter writes data.

Data_writer.auto_throttle enables automatic throttling in the com.rti.dds.publication.DataWriter so it can automatically adjust the writing rate and the send window size; this minimizes the need for repairing DDS samples and improves latency.
