Hi, I'm working on integrating Spark and a custom data source.
Most things go well with nice Spark Data Source APIs (Thanks to well designed APIs) But, one thing I couldn't resolve is that how to execute custom meta query for `ANALYZE TABLE` The custom data source I'm currently working on has a meta query so we can get MIN/MAX/Cardinality without full scan. What I want to do is that when `ANALYZE TABLE` is executed over the custom data source then execute custom meta query rather than executing Full Scanning. If this is not possible, I'm considering inserting stats into metastore_db manually. Is there any API exposed to handle metastore_db (e.g. insert/delete meta db)? Regards, Jason
