I prepared two neo4j instances called A, B installed on two machines. I sent the incremental storage files of A to B after inserted a node into A. I cannot see the change from B until I restart the B. Please tell me why. And what can I do to fit my expection, thanks.
You cannot just update the underlying storage files for a running instance.
That's not how a database usually works (probably except sqlite).
You should also use a recent version, not 3.5 which will be end of life soon
If you want to send deltas to the other instance, consider a CDC approach like with the kafka plugin.
