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 DURABILITY, 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.
final Duration_t service_cleanup_delay |
Controls when the service is able to remove all information regarding a data instances.
When the service cleanup delay is set to 0, disposed instances will be completely removed from the service. Only values of 0 and com.rti.dds.infrastructure.Duration_t.DURATION_INFINITE are currently supported.
[default] 0
HistoryQosPolicyKind history_kind |
The kind of history to apply in recouping durable data.
[default] com.rti.dds.infrastructure.HistoryQosPolicyKind.HistoryQosPolicyKind.KEEP_LAST_HISTORY_QOS
int history_depth |
Setting to use for the com.rti.dds.infrastructure.DurabilityQosPolicy.writer_depth when recouping durable data.
If the com.rti.dds.infrastructure.HistoryQosPolicy.depth is set to a value lower than this value, com.rti.dds.infrastructure.HistoryQosPolicy.depth will be set equal to the value of this field.
[default] com.rti.dds.infrastructure.DurabilityQosPolicy.AUTO_WRITER_DEPTH (1)
int max_samples |
Part of resource limits QoS policy to apply when feeding a late joiner.
[default] com.rti.dds.infrastructure.ResourceLimitsQosPolicy.LENGTH_UNLIMITED
int max_instances |
Part of resource limits QoS policy to apply when feeding a late joiner.
[default] com.rti.dds.infrastructure.ResourceLimitsQosPolicy.LENGTH_UNLIMITED
int max_samples_per_instance |
Part of resource limits QoS policy to apply when feeding a late joiner.
[default] com.rti.dds.infrastructure.ResourceLimitsQosPolicy.LENGTH_UNLIMITED
