Right. As we are introducing a mechanism where multiple operators can concurrently manage the same resources, a _locking_ mechanism is necessary. More generally to the rolling upgrade use-case, that mechanism would make sure that only a single operator manages the same resource at a single point in time. That would prevent issues where the label selectors for multiple operators intersect. Now on how to implement that _locking_ mechanism, I think we could reuse the approach used for locking by multiple replicas of the same operator, that is with a Lease resource, but owned by the Integration. The Lease resource seems the preferred mechanism (by client-go and controller-runtime), and handle use cases such as renewing and deadlining nicely. It would also be another extension of the locking implementation already in place for managing HA of the operator replicas. -- This is an automated message from the Apache Git Service.
