割り当ては、使用できるカウント可能な共有リソースの量を指定します。割り当ては、Dataform などの Google Cloud サービスによって定義されます。
システムの上限は固定値で、変更できません。
Google Cloud では、割り当てを使用して公平性を確保し、リソースの使用量と可用性の急増を抑えます。割り当ては、Google Cloud プロジェクトで使用できる Google Cloud リソースの量を制限します。割り当ては、ハードウェア、ソフトウェア、ネットワーク コンポーネントなど、さまざまなリソースタイプに適用されます。たとえば、割り当てによって、サービスへの API 呼び出しの数、プロジェクトで同時に使用されるロードバランサの数、作成可能なプロジェクトの数を制限できます。割り当てを適用することで、サービスの過負荷を防ぎ、Google Cloud ユーザーのコミュニティを保護します。割り当ては、自組織で使用している Google Cloud リソースの管理にも役立ちます。

Quotas are defined by Google Cloud services such as Dataform.\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 Dataform resources.\nSystem limits can't be changed.\n\nQuota replenishment\n-------------------\n\nDaily quotas are replenished at regular intervals throughout the day,\nreflecting their intent to guide rate limiting behaviors. Intermittent refresh\nis also done to avoid long disruptions when quota is exhausted.\nMore quota is typically made available within minutes rather\nthan globally replenished once daily.\n\nRequest a quota increase\n------------------------\n\nTo increase or decrease most quotas, use the Google Cloud console.\nFor more information, see\n[Request a quota adjustment](/docs/quotas/view-manage#requesting_higher_quota).\n\nCap quota usage\n---------------\n\nTo learn how you can limit usage of a particular resource by specifying a\nsmaller quota than the default, see\n[Cap usage](/docs/quotas/view-manage#capping_usage).\n\nRequired permissions\n--------------------\n\nTo view and update your Dataform quotas in the\nGoogle Cloud console, you need the same permissions as for any Google Cloud\nquota. For more information, see\n[Quota permissions](/docs/quotas/permissions).\n\nTroubleshooting\n---------------\n\nFor information about troubleshooting errors related to Dataform\nquotas and limits, see [Troubleshooting](/dataform/docs/troubleshooting).\n\nDataform quotas\n---------------\n\nDataform has the following API quotas:\n\nQuotas for services used by Dataform\n------------------------------------\n\nDataform uses other Google Cloud services. These services have\nproject-level quotas, which apply when you use Dataform.\n\nDataform uses the following Google Cloud services that\nhave their own quota limits:\n\n- [BigQuery](/bigquery/quotas)\n- [Identity and Access Management](/iam/quotas)\n- [Cloud Monitoring](/monitoring/quotas)\n- [Secret Manager](/secret-manager/quotas)\n\nDataform compilation resources limits\n-------------------------------------\n\nDataform enforces the following usage limits on compilation resources:\n\nAdditionally, Dataform imposes limits on CPU and memory use during compilation.\nIf these limits are exceeded when you compile your code, the compilation fails\nand Dataform throws a compilation error.\n\nTo estimate the compilation resources usage of your repository,\nsee [Estimate compilation resources usage of your repository](/dataform/docs/best-practices-repositories#estimate-comp-resource-usage-of-repo).\n\nYour repository might exceed the usage limits for the following reasons:\n\n- An infinite loop bug in the repository code.\n- A memory leak bug in the repository code.\n- Large repository size, approximately more than 1000 workflow nodes.\n- Large number of concurrent queries.\n\n| **Tip:** [Update Dataform core](/dataform/docs/manage-repository#manage-dataform-core-package) to the latest version to lower the risk of exceeding compilation limits.\n\nFor more information about repository size in Dataform, see\n[Overview of repository size](/dataform/docs/best-practices-repositories#overview-repo-size)."]]
