Viewing and Changing Join Keys in Your Data Model

Hi Yanisa S., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support.

To answer your question about viewing or changing the current join key of each table in Mixpanel's data model, I can provide some information based on the knowledge sources: The join keys for different types of tables in Mixpanel are handled as follows: 1. For User Profiles: The join key is always distinct_id and cannot be changed.2. For Group Profiles: You specify the group key when creating a new group profile. This key is then used to join events on that property.3. For Lookup Tables: You specify the join key when creating or uploading the lookup table.To view or manage these join keys: - For Lookup Tables, you can access them via Lexicon. Go to Lexicon > Import > Lookup Table to view existing lookup tables or upload new ones. Here you can see which properties are linked to each lookup table.- For Group Profiles, you would need to check the group key you specified when creating the group profile.It's important to note that a Mixpanel property can only be mapped to one lookup table in Lexicon. If you need to map different lookup tables for the same property, you have two options: 1. Create a local mapping within a specific report. 2. Create multiple custom properties containing the property you want to map, then map different lookup tables to each custom property in Lexicon.For more detailed information on managing lookup tables and their join keys, you can refer to the Lookup Tables documentation.Remember that only Project Owners and Admins can create global lookup table mappings, while Analysts and Consumers can only create local mappings within reports.
