# Node1
create table A (
    int id,
    string message
);

# Node2
let func1 = (schemaof(A) record, event) {
    print record, event;
};
sub table A on RECORD_INSERTED, RECORD_DELETED with func1;

# Node3
let func1 = (schemaof(A) record, event) {
    print record, event;
};
sub table A on RECORD_INSERTED, RECORD_DELETED with func1;
