COMPONENT | DESCRIPTION / VALUE |
---|---|
DomainType | Required. MMT_MARKET_MAKER = 9 |
Interactions | Conditional. Use the appropriate interactions according to your messaging needs: • InitialImage: true, indicates that an initial image is required. • InterestAfterRefresh: true, indicates that a streaming request is required. • Pause: true, indicates that a pause is required. |
Indications | Optional. ConflatedInUpdates: true, indicates that conflated updates are required. Batch and View request are specified in the Payload. |
QoS | Optional. Indicates the QoS at which the consumer wants the stream serviced. If both QoS and worstQos are specified, this request can be satisfied by a range of QoS. |
worstQos | Optional. Used with QoS to define a range of acceptable QoS. If the provider encounters such a range, it should attempt to provide the best possible QoS within that range. This should only be used on services that claim to support it via the SupportsQosRange item in the Source Directory response (for details, refer to Section 4.3.1.1). |
NOTE: Enterprise Message API provides the Request.Qos() method to set both Qos and WorstQos depending upon the timeliness and rate values. | |
Priority | Optional. Indicates the class and count associated with stream priority. |
