Collection and configuration limits

Collection limits

Analytics does not log events, event parameters, and user properties that exceed the following limits.

For detailed information about the error events that Analytics logs when you exceed the following collection limits, see Analytics Error Codes.

You cannot increase these limits by upgrading to the Flame or Blaze pricing plans. The limits are the same for all Firebase projects.
