About rate limits in CommCare
CommCare is a cloud-hosted platform engineered to provide optimal performance across all our users' project spaces. To ensure reliability, the system has built-in rate limits on the number of form submissions allowed per project space in a given period of time.
When CommCare rate limits a project space, all form submissions from CommCare Mobile and Web Apps will be saved locally until rate limiting expires, at which time those forms will be auto-synced to the server. Importantly, you will never lose a form submission due to rate limiting—rather, you may simply experience a delay between submission of a form and when that form is synced to the CommCare server.
When do rate limits apply?
Rate limits apply only when the entire CommCare platform is under high load, meaning your project will never experience rate limiting of form submissions during off-peak hours (as determined by real-time load patterns). When the system is under high load, CommCare applies rate limit caps on all project spaces.
What are the rate limit thresholds for my project space?
The rate limiting thresholds for your organization's project space are determined by the number of mobile workers included in your subscription plan:
MOBILE WORKERS INCLUDED IN SUBSCRIPTION
|TIME PERIOD||RATE LIMIT THRESHOLD|
|125 mobile workers||Form submissions per week||28,750|
|Form submissions per day||5,750|
|Form submissions per minute||17|
|250 mobile workers||Form submissions per week||57,500|
|Form submissions per day||11,500|
|Form submissions per minute||35|
|500 mobile workers||Form submissions per week||115,000|
|Form submissions per day||23,000|
|Form submissions per minute||70|
