Hi All,
We have created an application where we are using polling to get certain constant updates. Now this polling is client polling wherein the client polls the server at regular intervals to get the fresh data for certain actions.
Now we wish to take this to another level and implement Server Data Push so that the client does not keep polling unnecessarily and the server notifies the client as and when the data gets updated with the server. For this we have the DataService Transaction class that needs to be implemented.
But there are a couple of questions that are in my mind regarding this technology. It would be great if someone could answer them.
My questions are:
1) Does the LCDS server know which client to push data to in case of multiple clients looking at the same data scenario. e.g. Two clients A and B are looking at the same data. A performs an action and that action needs some time to get completed at the server. Now in case we use Server Data Push, will the LCDS be intelligent enough to send the message on completion of the requested activity to only A and not B.
2) In order to push data to the client, the server will invoke some method which will return the desired data to te client. How do we keep the parameters registered with the server that this method would need while getting invoked. SInce, the call to the method will not be client initiated, how does the server know what parameters to be passed to the method in order to invoke it. How will this work in a multi-user looking at the same data/screen scenario.
The answers to these questions will really help us. In case anyone is well versed with this technology, please pitch in to give your inputs.
Many Thanks.
