----------------------------------------
Summary: Introduce a optional property for conditional upsert
Key: HUDI-1936
URL: https://issues.apache.org/jira/browse/HUDI-1936
Project: Apache Hudi
Issue Type: New Feature
Components: Common Core, Compaction
Reporter: Biswajit mohapatra
Assignee: Biswajit mohapatra
Fix For: 0.7.0
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
