// Quota configuration helps to achieve fairness and budgeting in service
// usage.
//
// The quota configuration works this way:
// - The service configuration defines a set of metrics.
// - For API calls, the quota.metric_rules maps methods to metrics with
// corresponding costs.
// - The quota.limits defines limits on the metrics, which will be used for
// quota checks at runtime.
//
// An example quota configuration in yaml format:
//
// quota:
// limits:
//
// - name: apiWriteQpsPerProject
// metric: library.googleapis.com/write_calls
// unit: "1/min/{project}" # rate limit for consumer projects
// values:
// STANDARD: 10000
//
// # The metric rules bind all methods to the read_calls metric,
// # except for the UpdateBook and DeleteBook methods. These two methods
// # are mapped to the write_calls metric, with the UpdateBook method
// # consuming at twice rate as the DeleteBook method.
// metric_rules:
// - selector: "*"
// metric_costs:
// library.googleapis.com/read_calls: 1
// - selector: google.example.library.v1.LibraryService.UpdateBook
// metric_costs:
// library.googleapis.com/write_calls: 2
// - selector: google.example.library.v1.LibraryService.DeleteBook
// metric_costs:
// library.googleapis.com/write_calls: 1
//
// Corresponding Metric definition:
//
// metrics:
// - name: library.googleapis.com/read_calls
// display_name: Read requests
// metric_kind: DELTA
// value_type: INT64
//
// - name: library.googleapis.com/write_calls

// * One of the time intevals:
// * "/min" for quota every minute.
// * "/d" for quota every 24 hours, starting 00:00 US Pacific Time.
// * Otherwise the quota won't be reset by time, such as storage limit.
// * One and only one of the granted containers:
// * "/{organization}" quota for an organization.
// * "/{project}" quota for a project.
// * "/{folder}" quota for a folder.
// * "/{resource}" quota for a universal resource.
// * Zero or more quota segmentation dimension. Not all combos are valid.
// * "/{region}" quota for every region. Not to be used with time intervals.
// * Otherwise the resources granted on the target is not segmented.
// * "/{zone}" quota for every zone. Not to be used with time intervals.
// * Otherwise the resources granted on the target is not segmented.
// * "/{resource}" quota for a resource associated with a project or org.
//
// Here are some examples:
// * "1/min/{project}" for quota per minute per project.
// * "1/min/{user}" for quota per minute per user.
// * "1/min/{organization}" for quota per minute per organization.

// VERY_LOW, LOW, STANDARD, HIGH, VERY_HIGH
//
// To apply different limit values for users according to their tiers, specify
// the values for the tiers you want to differentiate. For example:
// {LOW:100, STANDARD:500, HIGH:1000, VERY_HIGH:5000}
//
// The limit value for each tier is optional except for the tier STANDARD.
// The limit value for an unspecified tier falls to the value of its next
// tier towards tier STANDARD. For the above example, the limit value for tier
// STANDARD is 500.
//
// To apply the same limit value for all users, just specify limit value for
// tier STANDARD. For example: {STANDARD:500}.
//
// To apply a regional overide for a tier, add a map entry with key
// "<TIER>/<region>", where <region> is a region name. Similarly, for a zone
// override, add a map entry with key "<TIER>/{zone}".
// Further, a wildcard can be used at the end of a zone name in order to
// specify zone level overrides. For example:
// LOW: 10, STANDARD: 50, HIGH: 100,
// LOW/us-central1: 20, STANDARD/us-central1: 60, HIGH/us-central1: 200,
// LOW/us-central1-*: 10, STANDARD/us-central1-*: 20, HIGH/us-central1-*: 80

// tier as well.
