In the streamMap definition, the serviceName element maps a column in the Event Stream Processor source stream to the service identifier that the adapter provides.

The identifier provided by serviceName can potentially be used to provide namespace scope for a RIC that was provided by two different services to which you subscribed.

Attributes

Name	Description	Requirement
key	true or false, depending on whether this column is part of the source stream's unique key	see Notes

Notes

You must use the key attribute to set the value to true. If this column is not part of the stream's key, you can omit this attribute.

Example

<streamMap name="marketByOrderStream">
        <itemName key="true"/>
        <!-- serviceName / -->
        <sequenceNumber />
        <itemStale/>
        <dataField name="BID"/>
        <dataField name="ASK"/>
        <dataField name="TRDPRC_1"/>
        <dataField name="ACVOL_1"/>
        <dateTimeField timeName="TIMACT" dateName="ACTIV_DATE"/>
</streamMap>

In this example, no column of the source stream is mapped to the service name provided by the adapter because it is commented out.
