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.
