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, and they 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

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) 25 MB
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
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
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
