To resolve the error "Number of properties are above 10000. Please reduce the number of event properties being exported" when exporting your events data to BigQuery, you need to reduce the number of unique event properties in your Mixpanel project. This error occurs because Mixpanel imposes a limit on the number of unique properties that can be exported to maintain performance and avoid exceeding table or column limits in the destination.Here are some steps you can take to resolve this issue:1. Review your event properties: Check your Mixpanel project for any implementation mistakes that might be causing an excessive number of unique properties. For example, you might be accidentally including unique identifiers (like UUIDs) in property names.2. Use Lexicon to identify and manage properties: Utilize Mixpanel's Lexicon feature to review your event properties and identify any that are not necessary or are causing the issue. You can hide or drop properties that are not needed for analysis Lexicon: Describe your events and data using a dictionary.3. Create a regex selector: Try to identify a regex selector that can filter out some properties from your schema. This can help reduce the number of properties being exported.4. Contact Mixpanel support: If you're unable to resolve the issue on your own, reach out to Mixpanel's support team for assistance. They can help you identify problematic properties and suggest solutions Data Pipelines FAQ> .5. Consider using a single table schema: When exporting to BigQuery, Mixpanel recommends using a single table schema, which creates a mp_master_event table with one column per unique property name across all events. This approach can help manage large numbers of properties more effectively BigQuery Integration.Remember, Mixpanel has a soft limit of 10,000 unique properties in your schema after transformation rules have been applied. Exceeding this limit will cause your pipelines to be paused until the issue is resolved.By implementing these steps, you should be able to reduce the number of properties being exported and successfully export your events data to BigQuery.
