[jira] [Created] (HUDI-8071) Handle skew for user defined sort columns in BULK_INSERT

Vinish Reddy created HUDI-8071:
----------------------------------

             Summary: Handle skew for user defined sort columns in BULK_INSERT
                 Key: HUDI-8071
                 URL: https://issues.apache.org/jira/browse/HUDI-8071
             Project: Apache Hudi
          Issue Type: Improvement
          Components: deltastreamer, writer-core
            Reporter: Vinish Reddy


If there is a skew in user defined columns for sortKey, spark sort reduces the number of tasks and this leads to an increase in contention when writing parquet files.
