RFA NONSTREAMING with BATCH request
I am using rfa 7.2.1 java implementation.
When I build a consumer batch request with NONSTREAMING indication flag, I don't receive any OMM_ITEM_EVENT, but only a COMPLETION_EVENT without payload.
The message request that I build is like this:
MESSAGE Msg Type: MsgType.REQUEST Msg Model Type: MARKET_PRICE Indication Flags: NONSTREAMING | REFRESH | BATCH_REQ Hint Flags: HAS_ATTRIB_INFO | HAS_PRIORITY Priority: 1,1 AttribInfo ServiceName: BBG NameType: 1 (RIC) Payload: None
If I remove the indication flag NONSTREAMING it works fine.
I would like to kindly ask if the batch request is snapshot by definition or if there can be both streaming and snapshot mode.
I've noticed that replacing the indication flag REFRESH with NONSTREAMING, works. The documentation states:
"Non-streaming requests are fulfilled by a provider sending a response message called a refresh."
Does this mean that NONSTREAMING and REFRESH indication flags are interchangeable?
Please be aware RFA 7.2 is now unsupported and especially for RSSL/OMM one should update to the latest version for many bug fixes and improved documentation. For new projects you should review EMA/Java which can significantly reduce the amount of effort need to consume data.
Batch Snapshot is a licensable feature - so the most likely explanation is that this feature is not licensed for your TREP installation.
Please contact your TREP / Market Data Admin team or TR account manager to discuss further.
To answer your question - you can make streaming or non-streaming(subject to licence) Batch requests.
