Payload in subscription

Why does subscription query return all the nodes in the result everytime a new node has been created? This increases the payload a lot.

Is there an efficient way to fetch only the data that has changed? Like only the add, update or deleted node?

Hi @yodaheis,

Thanks for the question. Awesome to see you here in the community!

Currently, Dgraph only supports subscriptions that return the result of a query at regular intervals. Would you mind elaborating on what you are trying to build?

Hi Tejas,

Like even for a simple chat application, everytime a new message has been added, the subscription query will return all the messages, instead of the new message(s) added.
What if I want to get messages sent after the last one I have received?
I can think of a couple of ways to workaround this, by structuring the query with parameters, but there are many limitations around it, especially since there is no cursor as a filter parameter
