We are having issues connecting to the same hash on multiple connections. Is this something that is supported? Can we subscribe to the same hash on multiple connections? do we get the same data on both connections?
This is supported, and you will receive the same data over all connections. Two separate connections are completely independant of each other, and do not know about each others existance.
Could you provide more details about the issues you are having? You are more than welcome to submit your query to DataSift Support if you do not want to share details about your issue publicly.
