The operation allocates quota for the amount specified in the service
configuration or specified using the quota metrics. If the requested
amount is higher than the available quota, request does not fail and
remaining quota would become negative (going over the limit)
Not supported for Rate Quota.
BestEffort
The operation allocates quota for the amount specified in the service
configuration or specified using the quota metrics. If the amount is
higher than the available quota, request does not fail but all available
quota will be allocated.
For rate quota, BEST_EFFORT will continue to deduct from other groups
even if one does not have enough quota. For allocation, it will find the
minimum available amount across all groups and deduct that amount from
all the affected groups.
CheckOnly
For AllocateQuota request, only checks if there is enough quota
available and does not change the available quota. No lock is placed on
the available quota either.
Normal
For AllocateQuota request, allocates quota for the amount specified in
the service configuration or specified using the quota metrics. If the
amount is higher than the available quota, allocation error will be
returned and no quota will be allocated.
If multiple quotas are part of the request, and one fails, none of the
quotas are allocated or released.
QueryOnly
Unimplemented. When used in AllocateQuotaRequest, this returns the
effective quota limit(s) in the response, and no quota check will be
performed. Not supported for other requests, and even for
AllocateQuotaRequest, this is currently supported only for whitelisted
services.
