How does lightstreamer handle pusing data to
We have an thick client application that makes use of the >.net client API. We also have a number of custom Data Adapters which support a number of different subscriptions (modes)...COMMAND, MERGE and RAW. We are working with the Presto version of Lightstreamer.
I was under the impression that if a Data Adapter pushed an update and that update was idential to what Lightstreamer had previuosly pushed last (i.e. had cached) to its subscribed clients, that the lightstreamer would not push that data again to its clients. We are not seeing this. What am I missing (what is the correct behavior).
For this discussion we are operatering in Command mode.
here are log files collected on our clients....
