Quotas and Limits
This page documents fine-grained limits and quotas for sending data to and querying data from Dash0 that apply to your configuration and telemetry you send to Dash0. To the best of our knowledge, you should never hit any of these limits with OpenTelemetry automatic instrumentations or any normal observability use-case.
