EMA Queries - dictionary download, item valid status and batch streaming

rinki121

Hello Team,

I have previously uses ETA java with value add api to consume data from reuters for Credit instruments ,and now exploring EMA api for consuming other kind of data and have few queries related to same:

1) In ETA, I was supplying dictionary from file for decoding fields. how to supply dictionary from file using EMA or how to download initial set of complete dictionary from provider.

2. In terms of stream states, when an item is considered invalid in terms of states?

3. Is it possible to request for streaming data for a list of items (in a batch) in one request?

Thanks

Hi @rinki121,

Yes, EMA is in many ways easier to use compared to ETA, and can do most of these tasks with configuration files.

I would recommend that you start from the Quickstart and move on to tutorials, since all these basic questions are answered in these resources. If you have any followup questions, you can ask them here.

Hello @rinki121

I want to add more information about the EMA API Dictionary Download and Batch feature.

The EMA API supports local dictionaries and dictionary downloads (from the Provider). The application can set it via the API configuration file. You can find more detail in the "Dictionary Types" section of the Enterprise Message API (EMA) - Configuration Overview article.

You can check the batch request EMA Java API example ex370_MP_Batch for more detail.

In terms of stream states, an item is considered invalid when the stream state is closed.
