> The suggestion came from [~lina.li] during the review for SENTRY-1821.
> We have several places where we rely on transactions to support
> read/modify/write semantics for incrementing IDs. This works but using DB
> support is rather expensive and we can user in-core serializations to help
> with this at least within a single node and rely on DB for multi-node
> synchronization.
> This isn't much of a problem for path updates since they are driven by
> HMSFollower which usually runs on a single leader node, but permission
> updates originate from clients directly and may be highly concurrent.
> We are internally serializing all permissions update anyway, so doing partial
> serialization on every node helps.
> The patch serializes all calls that affect permission updates.
