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 AI Applications 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 AI Applications.\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\n\nThere are also *system limits* on AI Applications resources.\nSystem limits can't be changed.\n| **Note:** Google Cloud products that use the Discovery Engine API, AI Applications (also known as Vertex AI Search) and Google Agentspace, share quotas. This means that your search and recommendations apps in Vertex AI Search share quotas with your apps in Google Agentspace.\n\nAllocation quotas\n\nThe following quotas don't reset over time. Instead, they're released when you\nrelease the resource. You can [request a quota increase](#request-a-quota-increase)\nif the default quota isn't enough.\n\n| Quota | Value |\n|--------------------------------------------------------------------------|----------------|\n| Total number of data stores per project | 100^\\*^ |\n| Total number of engines per project | 150^†^ |\n| Number of pending import long running operations per project | 300 |\n| Number of pending purge documents long running operations per project | 100 |\n| Number of serving controls per project | 1,000 |\n| Number of boost serving controls per serving config | 100 |\n| Number of filter serving controls per serving config | 100 |\n| Number of redirect serving controls per serving config | 100 |\n| Number of synonym serving controls per serving config | 100 |\n| Regional number of data stores per project per location (Global, US, EU) | 100 |\n| Regional number of documents per project per location (Global, US, EU) | 10,000,000 |\n| Regional number of engines per project per location (Global, US, EU) | 150 |\n| Regional number of user events per project per location (Global, US, EU) | 40,000,000,000 |\n\n\n^\\*^ Due to a technical limitation, the maximum quota for data stores is\n500 per project. If you need more data stores, use new projects.\n\n\n^†^ Due to a technical limitation, the maximum quota for engines is 500\nper project. If you need more engines, use new projects.\n| **Note:** The number of data stores, documents, user events, and engines across all locations can't exceed the total per-project quota for that resource. For example, if you already have 60 data stores in the `eu` multi-region and 40 in the `us` multi-region, you can't create another data store because the overall data store quota for the project is 100.\n\nRate quotas\n\nThe following quotas apply to AI Applications API requests. You can\n[request a quota increase](#request-a-quota-increase) if the default quota\nisn't enough.\n\n| Quota | Value |\n|---------------------------------------------------------------------------------------|--------|\n| Complete query requests per minute per project | 300 |\n| Conversational search read requests per minute per project | 300 |\n| Conversational search write requests per minute per project | 300 |\n| Document batch requests (such as inline import and purge) per minute per project | 100 |\n| Document async import (Cloud Storage, BigQuery, etc.) requests per minute per project | 5 |\n| Document purge requests per minute per project | 100 |\n| Document read requests per minute per project | 300 |\n| Document write requests per minute per project | 12,000 |\n| Evaluation create requests per day per project | 5 |\n| Evaluation read requests per minute per project | 100 |\n| Evaluation write requests per minute per project | 100 |\n| LLM query requests (search summarization, multi-turn search) per minute per project | 60 |\n| Number of pending FHIR or BigQuery streaming writes per minute | 6,000 |\n| Number of sample query sets per project | 100 |\n| Ranking API requests per minute per project | 500 |\n| Recommend requests per minute per project | 60,000 |\n| Sample query read requests per minute per project | 200 |\n| Sample query set read requests per minute per project | 100 |\n| Sample query set write requests per minute per project | 100 |\n| Sample query write requests per minute per project | 200 |\n| Schema read requests per minute per project | 100 |\n| Schema write requests per minute per project | 100 |\n| Regional search requests per minute per project per location (Global, US, EU) | 300 |\n| User event batch requests (such as import and purge) per minute per project | 100 |\n| User event collect requests per minute per project per user | 240 |\n| User event write requests per minute per project | 60,000 |\n\nQuota for web page indexing\n\nWhen you have a data store with\n[Advanced website indexing](/generative-ai-app-builder/docs/about-advanced-features#advanced-website-indexing)\nturned on, every web page that you index counts towards the \"Number of documents\nper project\" quota in the [Allocation quotas](#allocation-quotas) list. You can\nalso see the number of pages in your project and the page quota for that project\nin the **Project pages vs quota** field in the **Data** page for a data store.\n\nIf you add websites to a data store in a project and the web pages in those\nwebsites exceed the project's quota, the websites are not\nindexed. If you have websites in your data store that are already indexed, those\nwebsites continue to be indexed as before. You can request to [upgrade your\nquota](#request-a-quota-increase) at any time.\n\nRequest a quota increase\n\nTo adjust most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/help/request_increase)."]]
