I have currently started to deep dive into our company's Amplitude data and to understand the tool better I’ve read the official blogposts.
Eg.: https://amplitude.com/blog/event-data-components#next-steps
In the content I’ve read so far “user_id” is included in the event property and I now wonder why that is needed when user_id is part of the user properties connected to the event? User_id in both places should in that case be redundant?
Thanks in advance for your help.
Best,
Josefin
Hi
I’m not fully aware of the context of that blog post, but in almost all the events “user_id” isn’t usually part of event properties. It’s redundant in almost all the cases.
The only place it could be useful is if that user_id value captured is in context of actions performed by some other user. e.g. admin user action granting access to another user.
