Quotas and limits

This document lists the quotas and system limits that apply to Application Integration.

Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Application Integration.
System limits are fixed values that cannot be changed.

Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.

The Cloud Quotas system does the following:

Monitors your consumption of Google Cloud products and services
Restricts your consumption of those resources
Provides a way to request changes to the quota value

In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.

Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.

There are also system limits on Application Integration resources. System limits can't be changed.

By default, Application Integration quotas and limits apply on a per-project basis. Quotas and limits that apply on a different basis are indicated as such; for example, the default concurrent executions for each project, or the maximum numbers of integrations per project.

Resource quotas

The following quotas apply to Application Integration resources for each Google Cloud project. You can increase or decrease the quota by requesting for a quota change.

Resource	Quota	Value
Integration execution	Default concurrent executions per project	50
	Number of integration execution requests per minute	24000
	Number of days an integration execution can last, including the pause during the approval task	31 days
Integration Connectors	See Integration Connectors limits
Integration execution logs and monitoring	Number of read executions requests per minute	18000
Integrations page (This page lists all the available integrations in your project)	Number of read integration requests per minute	12000
Integration editor page (This page loads a whole integration including all the integration versions and configured task entities)	Number of read task entity requests per minute	12000
	Number of read integration version requests per minute	12000
	Number of write integration version requests per minute	12000
Authentication profiles page (This page lists all the available authentication profiles in your project)	Number of read requests per minute	12000
	Number of write requests per minute	12000
Salesforce trigger	Number of read Salesforce channel requests per minute	12000
	Number of write Salesforce channel requests per minute	12000
	Number of read Salesforce instance requests per minute	12000
	Number of write Salesforce instance requests per minute	12000

Request a quota increase

To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.

Usage limits

Application Integration enforces the following usage limits. Your are responsible for tracking and ensuring that the values stay within the prescribed limits. Exceeding the limits might lead to reduced throughput, task failures, and increased latencies when running the integration.

Resource	Limit	Value
Applicable to the entire Application Integration	Maximum characters in the integration name	64 characters
	Maximum cumulative size of all the integration data (including input and output variables) Note:Similar to integrations, each sub-integration also has a limit of 25 MB. However, when a private trigger is triggered from an integration, the size of both the integration and the private trigger is counted towards the limit, since they are in the same execution.	25 MB Caution: If the data size exceeds 10 MB, Application Integration runs the integration, but disables local logging. As a result, you can't view the full execution logs, apply retry strategy, or monitor integrations in the monitoring dashboard.
	Maximum cumulative size of all the integration data (including input and output variables) sent and received from connections	8 MB
	Timeout for synchronous (SYNC) integration executions The timeout duration includes any external system calls or sub-integration tasks of the integration during its execution. After the timeout duration, the execution status is set to `CANCELED`. Examples of external system calls include, calling external endpoints, calling Salesforce using connectors, and calling Google Cloud functions	2 minutes
	Timeout for asynchronous (ASYNC) integration executions If your sub-integration takes longer than 2 minutes to run, consider executing your integration in ASYNC mode	10 minutes
	Maximum time till which an older version of the integration can run after publishing the new version (system consistency) This is because Application Integration is a distributed system that provides eventual consistency. It uses caches throughout the system that may take time to clear and refresh	10 minutes
	Maximum numbers of integrations per project	1000
	Maximum number of tasks in an integration If there is a need for more tasks, it is recommended that you split your integration into multiple integrations	100
	Maximum versions allowed for an integration	100
API trigger	Maximum characters for TRIGGER_NAME in Trigger ID Trigger ID format: `api_trigger/TRIGGER_NAME`	64 characters
Apps Script task	Maximum active deployments for an Apps Script	50
	Queries per second (QPS) for API executables	5000 per minute
	Queries per second (QPS) for Webapp deployments	5000 per minute
	Latency for API executables	1.5 seconds
	Latency for Webapp	2.5 seconds
	Maximum cumulative size of all the integration variables in an Apps Script	15 MB
Call REST Endpoint task	Maximum number of concurrent REST calls	100
	Maximum size of the request from the REST endpoint	25 MB
	Maximum size of the response from the REST endpoint	25 MB
Call Integration task	Maximum number of sub-integrations that can run from the main integration	10000
Connectors task	Timeout for Connector task execution	3 minutes
Connectors task	Maximum size of the response from the connector	20 MB
While Loop task and For Each Loop task	Maximum cumulative size of data processed	20 MB
	Maximum number of iterations	8000
	Maximum cumulative size of data collected from each sub-integration call	50 MB
For Each Parallel task	Maximum cumulative size of data processed	20 MB
For Each Parallel task	Maximum number of parallel executions	50
Data Mapping task	Maximum size of an array data type variable	100000 elements
	Maximum size of a JSON data type variable	20 MB
	Maximum size of a string data type variable	20 MB
Data Transformer task	Maximum memory available for script evaluation	300 MB

Data processing limits

We don't recommend using integrations in the following scenarios:

Integration requires movement of bulk data or focus on extract, transform, and load (ETL) processes
Cumulative size of all the integration data is greater than 10 MB during execution
When calculating the cumulative data size, add the size of all types of data such as input variables, output variables, and other intermediate task variables

Caution: If the data size exceeds 10 MB, Application Integration runs the integration, but disables local logging. As a result, you can't view the full execution logs, apply retry strategy, or monitor integrations in the monitoring dashboard.
