> Currently partition stats avoids data skipping if even one of the query filters has a null, value count based expression. Or if any query uses a complex expression like expression index.
> The jira aims to fix the logic so that index only filters out such queries and performs pruning based on the other queries.
> For example Spark automatically adds query isNotNull on a column like:- isnotnull(driver#869) when an equality query on driver is used. We can ignore such queries for partition stats.
