Functions rate limit

Rate limiting helps prevent recursive functions from running indefinitely.

You may have received an error or notification regarding rate limits or concurrency when running your functions.

If a function is invoked with the same document more than 200 times within 30 seconds, we don't execute further function calls until the rate drops below this limit.

If functions from a single project are invoked more than 4,000 times within 30 seconds, we don't execute further function calls until the rate drops below this limit. This limit is to prevent a single project with many documents from all running at the same time and using up all of our concurrency.

To prevent these errors, use caution in situations where a function causes a mutation that triggers itself.

If you're using @sanity/client v7.12.0 or later, it limits recursive function chains to 16 invocations.
