Hooks / validators with multiple oak-core instances using the same
backend storage
Hi,
I have a question about the hooks / validators in oak-core: let's assume multiple oak-core instances use the same backend storage, do the hooks / validators also see changes made within other oak-core instances? If yes, does it scale? I mean, let's assume we have 100 cluster nodes, would each cluster node validate each change made by all other cluster nodes?
Regards,
Thomas

No, a hook only looks at a commit *before* it gets sent to the
underlying MicroKernel and thus shared with the rest of the cluster.
