>             Fix For: 0.9.0

>
> If anyone wants to use custom upsert logic then they have to override the Latest avro payload class which is only possible in java or scala . 
> Python developers have no such option . 
> Will be introducing a new payload class and a new key which can work in java , scala and python 
> This class will be responsible for custom upsert logic and a new key hoodie.update.key which will accept the columns which only need to be updated 
>  
> "hoodie.update.keys": "admission_date,name",  #comma seperated key 
> "hoodie.datasource.write.payload.class": "com.hudiUpsert.hudiCustomUpsert" #custom upsert key 
>  
> so this will only update the column admission_date and name in the target table
