>
> 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
