BEST_EFFORT

org.omg.dds.core.policy.Reliability.Kind.BEST_EFFORT

Indicates that it is acceptable to not retry propagation of any samples.

Presumably new values for the samples are generated often enough that it is not necessary to re-send or acknowledge any samples. This is the default value for org.omg.dds.sub.DataReaders and org.omg.dds.topic.Topics.

RELIABLE

org.omg.dds.core.policy.Reliability.Kind.RELIABLE

Specifies the Service will attempt to deliver all samples in its history.

Missed samples may be retried. In steady-state (no modifications communicated via the org.omg.dds.pub.DataWriter) the middleware guarantees that all samples in the DataWriter history will eventually be delivered to all the org.omg.dds.sub.DataReader objects. Outside steady state the org.omg.dds.core.policy.History and org.omg.dds.core.policy.ResourceLimits will determine how samples become part of the history and whether samples can be discarded from it. This is the default value for DataWriters.
