Hi Folks: I have implemented a data source v2 API for an internal source. As a consequence of generating the data source, we have bunch of statistical information about the source which i can potentially use, only if spark pushes down the aggregates down to the data source itself.
I see that there is already a comprehensive Jira for the same: https://issues.apache.org/jira/browse/SPARK-22390. Are there any more blockers for this Jira? I'll be more than happy to contribute if no one else had picked it up. Regards, Arun
