Controls the criteria used to determine the logical order among changes
made by
Publisher entities to the same instance of data (i.e.,
matching Topic and key). |
interface |
Durability
This policy expresses if the data should "outlive" their writing time.

LatencyBudget
Specifies the maximum acceptable delay from the time the data is written

Specifies the maximum duration of validity of the data written by the

interface |
Reliability
This policy indicates the level of reliability requested by a
DataReader or offered by a DataWriter . |
interface |
ResourceLimits
Specifies the resources that the Service can consume in order to meet the
requested QoS.
