Quotas & Limits¶
Limits and quotas are tied to your user account and apply to all requests you make.
Various limits and quotas apply to each service and operation. The most common types of limits are Rate Limits and Usage Quotas.
Rate limits are used to prevent overloading the Descartes Labs Platform with too many
concurrent requests. Rate limits are specified as number of requests/unit of time.
Compute time limits are used to prevent overloading the Descartes Labs Platform with too many
computationally intensive requests. The amount of computation resources required to return the
results of a search request vary greatly based on the search parameters, and similarly with
rastering requests. If too many complex requests are sent to our platform within a designated
time frame by a single user, the service will return a RateLimitExceeded error. The values
of these limits are expressed as number of seconds of compute time/unit of time and
represent aggregated usage across all queries in the unit of time.
Usage quotas keep track of how much you use the Descartes Labs Platform and prevent you from accessing the platform after your quota has been reached. Each service measures usage differently, see below for details on how usage is measured and limited. Usage quotas are typically reset monthly. Contact support@descarteslabs.com for help with usage quotas.
