Amplitude introduced the , client_event_time, parameter on July 16, 2014. Earlier events do not have the , client_event_time, parameter, which means we cannot form the primary key for them and thus cannot deduplicate the data. Other tables (except , EVENT_TYPE, ) depend on the , EVENT, table. Therefore, to maintain data integrity, we sync Amplitude data from July 16, 2014 onwards., Schema information, This schema applies to all Amplitude connectors., To zoom, open the ERD in a new window]
