[jira] [Comment Edited] (SPARK-22390) Aggregate push down
[ https://issues.apache.org/jira/browse/SPARK-22390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16946140#comment-16946140 ]

-------------------------------------------------------------
I am slowly catching up the changes in Data Source V2 and try to fit aggregate push down there. It seems JDBC support is still not in Data Source V2 yet. If I put aggregate push down in V2, I don't have a data source to test the implementation. I guess all I can do is to follow the pushFilters in DataSourceV2Suite and implement a simple aggregate in AdvancedDataSourceV2, something like the GreaterThan filter. Any suggestions? [~smilegator]
