Push and Subscription Buffering

[wwatts]

Yes we seem to be experiencing different behavior. We had an update to a snapshot that was over 1000 items. We received the first 1000 items and then received that we lost raw updates on the remainder of the updates. When we changed the value for max_buffer_size in the conf file, we received all updates.

Some more information that may be helpful is that this behavior was on a demo license. We have not tried a similar situation on our production instance.

It is important that the snapshot is formally identified as a snapshot by the Data Adapter when it invokes update / smartUpdate on the supplied events.
Obviously, the snapshot kept internally by the Server to manage subsequent subscriptions doesn't have such problem, hence I assume that the issue occurs on the first subscription of the item.
May you please ensure that?

On the other hand, updates that are not part of the snapshot can be lost if they fill the protection buffer.

The license should not impact, but different editions (e.g. Moderato, Vivace) impact on the speed with which the updates are sent.
By the way, is your item subscribed to with the "unfiltered" flag?
