Hyukjin Kwon created SPARK-12126:
------------------------------------
Summary: JDBC datasource processes filters only commonly pushed
down.
Key: SPARK-12126
URL: https://issues.apache.org/jira/browse/SPARK-12126
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Hyukjin Kwon
As suggested
[here](https://issues.apache.org/jira/browse/SPARK-9182?focusedCommentId=14955646&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14955646),
Currently JDBC datasource only processes the filters pushed down from
{{DataSourceStrategy}}.
Unlike ORC or Parquet, this can process pretty a lot of filters (for example, a
+ b > 3) since it is just about string parsing.
As
[here](https://issues.apache.org/jira/browse/SPARK-9182?focusedCommentId=15031526&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15031526),
using {{CatalystScan} trait might be one of solutions.
