Thank you for your quick response @schroeder-
So it is implied that order or the values in response is same as the order of nodeid's in 'nodes' ?
are we safe to assume that?
from opcua-asyncio.
Yes they are always in the same order.

Hi Alex, just a small query, what is the limit to the count of nodes I can query at a time?
from opcua-asyncio.
There can be limits, see https://reference.opcfoundation.org/Core/Part5/v104/docs/6.3.11, but not all servers expose that value. I would make the max query value configurable and limit it to 10000 per request.
