The TokenStore is configured by a QuotaConfig for a protocol (EPP/WHOIS). It accepts concurrent take, put and refresh request to grant/accept token to the caller. The QuotaManager contains a TokenStore and provides abstractions that are appropriate for a quota leasing entity to use. Quota return calls are executed asynchronously by the QuotaManager, and quota refresh tasks are scheduled by the QuotaManager to run periodically. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=182109341
