[default] RTI Connext does not need to keep any samples of data instances on behalf of any com.rti.dds.subscription.DataReader that is unknown by the com.rti.dds.publication.DataWriter at the time the instance is written.
In other words, RTI Connext will only attempt to provide the data to existing subscribers.
This option does not require RTI Persistence Service.

RTI Connext will attempt to keep some samples so that they can be delivered to any potential late-joining com.rti.dds.subscription.DataReader.
Which particular samples are kept depends on other QoS such as com.rti.dds.infrastructure.HistoryQosPolicy and com.rti.dds.infrastructure.ResourceLimitsQosPolicy. RTI Connext is only required to keep the data in memory of the com.rti.dds.publication.DataWriter that wrote the data.
Data is not required to survive the com.rti.dds.publication.DataWriter.
For this setting to be effective, you must also set the com.rti.dds.infrastructure.ReliabilityQosPolicy.kind to com.rti.dds.infrastructure.ReliabilityQosPolicyKind.RELIABLE_RELIABILITY_QOS.
This option does not require RTI Persistence Service.

Which particular samples are kept depends on other QoS such as com.rti.dds.infrastructure.HistoryQosPolicy and com.rti.dds.infrastructure.ResourceLimitsQosPolicy. RTI Connext is only required to keep the data in memory and not in permanent storage.
Data is not tied to the lifecycle of the com.rti.dds.publication.DataWriter.
Data will survive the com.rti.dds.publication.DataWriter.
This option requires RTI Persistence Service.
