   yeah. its mainly bcoz of spark-sql. in spark-datasource, default key gen is SimpleKeyGen. 
   @xushiyan @YannByron : do we know why we have custom key gen as default in spark-sql. 
   but I didn't know that _hoodie_record_key value will be of the format "recordkeyFieldName:value". I checked the code and apparently for ComplexKeyGen and GlobalDeleteKeyGen we prefix the field name. 
   
   @xushiyan : we may need to solve this discrepancy.
