API ReferenceQuotas

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

Query parameters

waitbooleanOptionalDefaults to false

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

Quota configuration to apply
enabledbooleanOptionalDefaults to false
Whether the limits below are enforced.
max_resident_memory_percentinteger or nullOptional1-100

Reject memory-consuming updates once process resident memory reaches this percentage of total system memory (or of the cgroup limit, if one applies).

max_disk_usage_percentinteger or nullOptional1-100

Reject disk-consuming updates once the filesystem hosting the storage directory is filled to this percentage of its capacity.

release_margin_percentinteger or nullOptional0-100

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.
