Hyukjin Kwon created SPARK-17719:
------------------------------------
Summary: Unify and tie up options in a single place in JDBC
datasource API
Key: SPARK-17719
URL: https://issues.apache.org/jira/browse/SPARK-17719
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Hyukjin Kwon
Priority: Minor
- JDBC options are arbitrarily located as {{Map[String, String}},
{{Properties}} and {{JDBCOptions}}. It'd be great if we can unify the usages.
- Also, there are several options not placed in {{JDBCOptions}} which are,
{{batchsize}}, {{fetchszie}} and {{isolationlevel}}. It'd be good if we put
them together.
- {{batchSize}} and {{isolationLevel}} are undocumented.
- We could verify and check the argument before actually executing. For
example, it seems {{fetchsize}} is being checked after execution and it seems
throwing an exception wrapped by {{SparkException}}.
