Various settings to configure the external RTI Persistence Service used by RTI Connext for DataWriters with a com.rti.dds.infrastructure.DurabilityQosPolicy setting of com.rti.dds.infrastructure.DurabilityQosPolicyKind.DurabilityQosPolicyKind.PERSISTENT_DURABILITY_QOS or com.rti.dds.infrastructure.DurabilityQosPolicyKind.DurabilityQosPolicyKind.TRANSIENT_DURABILITY_QOS.
When a DataWriter's com.rti.dds.infrastructure.DurabilityQosPolicy.kind is com.rti.dds.infrastructure.DurabilityQosPolicyKind.DurabilityQosPolicyKind.PERSISTENT_DURABILITY_QOS or com.rti.dds.infrastructure.DurabilityQosPolicyKind.DurabilityQosPolicyKind.TRANSIENT_DURABILITY_QOS, an external service, the RTI Persistence Service, is used to store and possibly forward the data sent by the com.rti.dds.publication.DataWriter to com.rti.dds.subscription.DataReader objects that are created after the data was initially sent.
This QoS policy is used to configure certain parameters of the Persistence Service when it operates on the behalf of the com.rti.dds.publication.DataWriter, such as how much data to store. For example, it configures the HISTORY and the RESOURCE_LIMITS used by the fictitious DataReader and DataWriter used by the Persistence Service. Note, however, that the Persistence Service itself may be configured to ignore these values and instead use values from its own configuration file.
