Datastream limits the maximum rates of incoming requests and enforces appropriate quotas on a per-project basis. Specific policies vary depending on resource availability, user profile, service usage history, and other factors, and are subject to change without notice.
Datastream has the following quota limits:
Each Google Cloud project can have a maximum of 50 stream resources per region.
Each Google Cloud project can have a maximum of 5 private connectivity configurations.
Each user can make up to 1,200 API calls per minute.
Salesforce API quotas
Salesforce defines a limit for the total number of inbound API requests
during a 24-hour period for an org. We recommend carefully considering your
polling interval values and the number of objects that you want to replicate.
To find out what limits there are in place for your org, use the Salesforce
Limits API.
Write to BigQuery and Cloud Storage
When writing data into BigQuery and Cloud Storage, the quotas and limits for BigQuery and Cloud Storage apply.
Cloud Logging
Datastream saves logs in Cloud Logging. The Logging quota applies to your Datastream resources.
