Abstract
Embodiments enable clients to have read-write access to a stream where all other clients are aware of all changes being made to the stream. A pravega node can track the data that has been written to the stream. The clients can dynamically read the stream. A client among the clients can update the stream by sending a request to the pravega node that includes the update and a total length of the stream that was written to the stream at the time of the last read update by the client. If the total length of the stream received from the client matches the actual length of the stream maintained by the pravega node, the pravega node will update the stream. If not, a failure message can be sent to the client and the client can process more reads to the stream before making another attempt to update the stream.
