Subscribe to Ticker List updates without performance problem #21

Closed glikoz closed 2 years ago

glikoz commented 2 years ago

I have to write such kind of code to subscribe ticker updates for symbol list:

foreach (var symbol in symbols) { var res=await socketClient.SubscribeToTickerUpdatesAsync(symbol, async bookPrice => {});

Does It cause a performance problem for my system? Is there any way to combine these subscriptions to get rid of performance problems?

Thx for advance.

It depends, if you can handle the data coming in fast enough then it's fine. The library will automatically combine 10 subscriptions on a single connection, which you could increase with the SocketSubscriptionsCombineTarget client option.

There is not really a way to combine the call for multiple symbols as the API only support a subscription per symbol. So if I we're to accept multiple symbols in the call it would mean doing the same as you're doing now; just looping over the symbols.
