Consider the input data stream as the “Input Table”. Every data item that is arriving on the stream is like a new row being appended to the Input Table. A query on the input will generate the “Result Table”. Every trigger interval (say, every 1 second), new rows get appended to the Input Table, which eventually updates the Result Table. Socket API is the fastest we have made so far. Socket API allows you to get access to real time data for any get requests (see references for all the types of requests you can make). This is our recommended method for the API usage.A socket token can be fetched using /socket/token endpoint.

Double-click the node to configure it. Set the type as Listen on. In the Path section, you define an endpoint that clients can connect to by adding a new websocket-listener with the path /ws/receiveMessage. Level 1 and Level 2 are recommended for polling. For the most up-to-date data, consider using the websocket stream. Level 3 is only recommended for users wishing to maintain a full real-time order book using the websocket stream.
