Corda State Events : Do events have an order?

votes

A network consist of 3 nodes, where 1 node is read-only and participates in every transaction. Request can start from either of the nodes which in turn creates a request state. It is received and processed by other node to create a new response state. Both only issue new states and do not consume the state. Both these state events are received by the read-only node. Would the State events received by the read-only corda node have an order or would it be processed in any order ?

For eg can we say that the request originator state event would be received/processed first and then the other node ? or can it be possible under high load that the other node request gets received/processed by the read-only node first and then the originators event is received.

My experience with corda is very minimal and need to understand

how events are received by the parties when one party acts as read-only and all remaining parties only issue new states.

It depends on how the transactions is made.you are saying request state is issued and then response , ideally, order will remain same if you are dealing this in separate transaction. Anyways , question is too broad . – manish

In general, the order of the receiving messages is not guaranteed. A node will process messages in the order it receives them. But it's not guaranteed that the received messages are sequential.

If Node A is receiving messages from Node B and Node C, and Node B produces a message before node C. There is no guarantee that the message from Node B is processed first. The one which reaches Node A first gets processed first. The delay could be because of multiple reasons like network latency, etc.
