             Summary: sort the inputs by record keys for bulk insert tasks
                 Key: HUDI-5651
                 URL: https://issues.apache.org/jira/browse/HUDI-5651
             Project: Apache Hudi
          Issue Type: Improvement
            Reporter: vortual


BulkInsert adds an option to sort by primary key: 
WRITE_BULK_INSERT_SORT_INPUT_BY_RECORD_KEY

The advantage of sorting data according to the primary key: Flink needs to scan 
fewer files when new data is added later, and the memory usage will also be 
reduced
