[jira] [Created] (SPARK-25187) Revisit the life cycle of ReadSupport instances.

Wenchen Fan created SPARK-25187:
-----------------------------------

             Summary: Revisit the life cycle of ReadSupport instances.
                 Key: SPARK-25187
                 URL: https://issues.apache.org/jira/browse/SPARK-25187
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
    Affects Versions: 2.4.0
            Reporter: Wenchen Fan


Currently the life cycle is bound to the batch/stream query. This fits streaming very well but may not be perfect for batch source. We can also consider to let {{ReadSupport.newScanConfigBuilder}} take {{DataSourceOptions}} as parameter, if we decide to change the life cycle.
