## Event Object Elements

The elements (member variables) of each Event object, available to programmers when writing feature extractors. The right-hand side shows which database column(s) are mapped to a given element.

**session_id** = Column '*session_id*' (index 0)  
**app_id** = Column '*app_id*' (index 1)  
**timestamp** = Column '*timestamp*' (index 2)  
**event_name** = Column '*event_name*' (index 3)  
**event_data** = Column '*event_data*' (index 4)  
**event_source** = Column '*event_source*' (index 5)  
**app_version** = Column '*app_version*' (index 6)  
**app_branch** = Column '*app_branch*' (index 7)  
**log_version** = Column '*log_version*' (index 8)  
**time_offset** = Column '*offset*' (index 9)  
**user_id** = Column '*user_id*' (index 10)  
**user_data** = Column '*user_data*' (index 11)  
**game_state** = Column '*game_state*' (index 12)  
**event_sequence_index** = Column '*index*' (index 13)
