配额用于指定您可以使用的可计数共享资源的数量。配额由 Cloud Vision 等 Google Cloud 服务定义。
系统限制是无法更改的固定值。
Google Cloud 使用配额来帮助确保公平性并减少资源使用和可用性的激增。配额用于限制您的 Google Cloud 项目可使用的Google Cloud 资源的数量。配额适用于一系列资源类型，包括硬件、软件和网络组件。例如，配额可以限制对某项服务的 API 调用次数、您的项目并发使用的负载均衡器数量或者您可以创建的项目数量。配额可以防止服务过载，从而保护Google Cloud 用户社区。配额还可以帮助您管理自己的 Google Cloud 资源。

Quotas are defined by Google Cloud services such as Cloud Vision.\n- *System limits* are fixed values that cannot be changed.\n\nGoogle Cloud uses quotas to help ensure fairness and reduce\nspikes in resource use and availability. A quota restricts how much of a\nGoogle Cloud resource your Google Cloud project can use. Quotas\napply to a range of resource types, including hardware, software, and network\ncomponents. For example, quotas can restrict the number of API calls to a\nservice, the number of load balancers used concurrently by your project, or the\nnumber of projects that you can create. Quotas protect the community of\nGoogle Cloud users by preventing the overloading of services. Quotas also\nhelp you to manage your own Google Cloud resources.\n\nThe Cloud Quotas system does the following:\n\n- Monitors your consumption of Google Cloud products and services\n- Restricts your consumption of those resources\n- Provides a way to [request changes to the quota value](/docs/quotas/help/request_increase) and [automate quota adjustments](/docs/quotas/quota-adjuster)\n\nIn most cases, when you attempt to consume more of a resource than its quota\nallows, the system blocks access to the resource, and the task that\nyou're trying to perform fails.\n\nQuotas generally apply at the Google Cloud project\nlevel. Your use of a resource in one project doesn't affect\nyour available quota in another project. Within a Google Cloud project, quotas\nare shared across all applications and IP addresses.\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase).\n\n\nThere are also *system limits* on Vision resources.\nSystem limits can't be changed.\n\nQuota types\n-----------\n\nThere are 3 kinds of quota:\n\n1. Request Quota\n - The quota counts **per request sent** to Vision API endpoint.\n2. Feature Quota\n - The quota counts **per image / page sent** to Vision API endpoint.\n - Unless specified explicitly, quota with feature name as prefix is generally a Feature quota.\n - For `files:annotate` requests, if the `pages` field is not specified explicitly, the quota will count 5 pages per file. However, users will only be billed for the actual number of pages processed.\n3. In Processing Quota\n - The quota counts **per image / page being processed by Vision API** unless specified explicitly.\n - Can be inferred by \"in processing\" in quota name.\n - This quota determines the maximum number of images/pages that Vision API processes at a time for the asynchronous methods. Users can send more than this quota into the asynchronous methods, but the images/pages over the quota are not processed immediately. The files in excess of the quota are added to a queue to be processed later.\n\nThe current API usage quotas for the Vision API are as follows (and are\nsubject to change):\n\n| **Note: Celebrity recognition** is deprecated. Before requesting quota, review the conditions for approval in [Celebrity recognition](/vision/docs/celebrity-recognition).\n\nThese limits apply to each Google Cloud console project and are shared across\nall applications and IP addresses using that project.\n\nLower quotas can be set per user in the\n[Google Cloud console](https://console.cloud.google.com/iam-admin/quotas).\n\n### Quota increases\n\nYou can edit your quotas up to their maximum values by selecting\n**EDIT QUOTAS** from the **Quotas** page of the\n[Google Cloud console](https://console.cloud.google.com/iam-admin/quotas) page.\nTo request an increase above the maximum quota, edit your quota with your\nrequested increase and justification and submit your update. You will be\nnotified when your request has been received. You might be contacted for more\ninformation regarding your request. After your request has been reviewed, you\nwill be notified whether it has been approved or denied.\n\nGenerally each quota has \"per project per user\" and \"per project\" variants,\nplease change them correspondingly to your setup.\n\nWhen requesting feature a quota increase, consider the overall request quota\nand intended batch size to assure the following:\n\n- overall request quota (Requests per minute) \\* your batch size \\\u003e= increased feature quota\n\nIf you do not fulfill this requirement, you will still be throttled by the\noverall request quota.\n\nThis document contains current content limits and request quotas for the\nVision API. This page will be updated to reflect any changes to these\nrestrictions and usage limits.\n\nLimits\n------\n\nThe Vision API enforces the following usage limits:\n\nBase64-encoded images may exceed the JSON size limit, even if they are within\nthe image file size limit. Larger images should be hosted on Cloud Storage or\nat a publicly-accessible URL. Note that base64-encoded images can have a larger\nfile size than the original image file (usually about 37% larger)."]]
