Hi Atejero,

I confirm you that it is not possible to ensure that the Data Adapter sends the Snapshot for each new client that subscribes to a given Item.

The Snapshot should be considered as a set of fields that define the complete state of an item at a certain time.
So, against the first subscription for an Item the Lightstreamer server expects to be feeded with an initial Snapshot from the Data Adapter, and then in the face of real-time updates the server shall maintain an updated image of the Snapshot and make it available to any new clients that subscribe to that Item.
Please can you explain why the Snapshot provided by the server is not good for your client (than the first) needs?

Furthermore, please consider that if you want that your Adapters were notified for each client that subscribes to a particular Item you should use the notifyNewTables and wantsTablesNotification of Metadata Adapter Interface. And, if it is the case, you should let the Metadata comunicate with the Data Adapter.
