Set global quotas
Replace the cluster-wide resource quota configuration. The new configuration is propagated to every peer through consensus and persisted, so it survives restarts
Authentication
Authorization key, either read-write or read-only
Bearer authentication of the form Bearer <token>, where token is your auth token.
Query parameters
If true, wait until the new configuration is confirmed by consensus on this peer. If false - the request returns as soon as the change is proposed.
Request
Reject memory-consuming updates once process resident memory reaches this percentage of total system memory (or of the cgroup limit, if one applies).
Reject disk-consuming updates once the filesystem hosting the storage directory is filled to this percentage of its capacity.
How many percentage points below its limit a resource has to fall before this node starts accepting work again.
Without a margin, a resource resting on its limit crosses it in both directions on the noise between two readings, putting the node in and out of service each time — and restarting a shard recovery with it. Raise it where usage is volatile; 0 disables the margin and releases as soon as usage is back under the limit.
Unset leaves the built-in default in force, so a config written today does not pin a number that a later release may want to revise.
