ngjaying commented on issue #3208: Is state shared by function instances? URL: https://github.com/apache/pulsar/issues/3208#issuecomment-448833291 OK. I am concerned about the Read-Modify-Write scenario. For below scenario, given the initial value for state.key = "value". If the function has the below logic: ` String currentValue = context.getState("key"); context.putState("key", currentValue + context.getInstanceId); ` If this function is run with --parallelism 2. Is this read-modify-write run like a database transaction? If not, is there a best practice for such scenario.
