Description
Make Table provider implementation directly create physical plan from manifest file entries. File level statistics are aggregated into table level statistics which is available for count optimization.
Note: Aggregate Statistics will only take effect for time range which lie exactly on minute boundary. Otherwise they are treated as partial filters and plan changes, hence will not use statistics anymore.
