will websockets be able to consume dataType 2 ?

graham.street

My inhouse RTDS has two types of service. One with dataType 6 (IDN, Bloomberg etc) and dataType2 (inhouse services)

I am using the examples that came with the websockets API. Work fine with dataType 6 but I get a Json conversion error for the dataType 2. Is there a way to make the websockets examples consume dataType 2 ?

According to the servicegroup.cpd file

<serviceGroupName>.serviceGroup*dataType: { 1 - N }

Indicates the format of the data provided by this service group.

     1 - standard ANSI Page format

     2 - standard Marketfeed Record format

     6 - standard Refinitiv Wire format


Default value: 6

When I looked in the ads_websocke.cpd ffile I did see this, which answers my question :)

@B@MN@S@LFalse,True@True@ALLOW WS CONNECTIONS@ adsallowWSConnections : True
#help
allowWSConnections: { True, False }

Enables the WebSocket server for clients to access the JSON encoded data.


WARNING: Marketfeed services (dataType : 2) are NOT supported with WebSockets

as there is no direct conversion from Marketfeed to JSON. Marketfeed services

must be converted to RWF by setting the dataType to 6 in either the ADH or ADS/POP

which will force automatic conversion from Marketfeed to RWF for the entire service

prior to conversion to JSON.


Default value: True
