How to clean streaming connection through websocket api
Best Answer

Hi @lzhuang1
If you mean by "clean streaming connection" is to close streaming subscriptions, you will need to issue a Close request. You can find more details within the documentation. Alternatively, you can disconnect your connection to the server. The server will no longer keep active streams open. However, if you are looking to "clean" you connection by disconnecting, then later wish to reopen new streams, you will of course need to reconnect.

Hi Nick, thanks for your prompt response! By saying "Close request" do you mean login close request? I don't want to logout though, what I want is keep the login state but just recall all streaming requests to save traffics, and I might resend a streaming request in the future if needed, is that possible? Many thanks!

Hi @lzhuang1,
What I mean by "Close request" is not the login request but rather a request to close an individual opened item stream. For example, once you have successfully logged in to the server, you begin to open streaming requests. At anytime, you can close one of these item requests - refer to the documentation link I provided above. You can reopen them at anytime. If you haven't already, I would encourage you to work through the Quick Start to gain a better understanding of the operation. I would then work through the tutorial section that provides a deeper understanding of the concepts. Within the tutorial section you will find some details related to Closing Event Streams.

Hi @nick.zincone, thanks, I will take a look at the documentation. Another question, is there any problems with a long running stream request? I have to clean the requests because I found that if I have many streaming requests all of which are long-running (more than 24 hours), the responses will be stop at some point. Is there parameter in the request controls the lifetime of the streaming requests? Thank you!

@nick.zincone If we send close request with login request ID then will it cancel all streaming quote requests?
Or should we send close all individual streaming quotes and then close the login request?

Yes, when you send a close request using the login ID, this will log you out of the session and you will no longer receive updates. In fact, the server will eventually close the connection. Alternatively, you can send a Close() on the WebSocket and it should do the same.
If it is your goal is to keep the connection active, then you will have to close each individual stream.
