Generally speaking, the Amplitude architecture is based on pre-aggregated sets by the hour, day, week and month for users and events. While this allows the platform to scale well, one tradeoff is immutable data.
This article covers some frequently asked questions about how to modify or delete historical data.
How do I modify events that have already been ingested by Amplitude?
I updated user properties using the Identify API. Why are there still 'none' values in my charts?
I accidentally sent an event for a user. How do I delete this specific event for this specific user?
How do I backfill historical data into Amplitude?
Thanks for your feedback!
