Thanks @rdettai for the confirmation. Yes, I was thinking of enabling stats in the context of query optimization. > This will be very long if there are many files. It might actually be faster to just get the list of files and distribute the work across nodes (especially if you have many nodes). One thing I have noticed in existing system is to leverage distributed compute for this kind of metadata gathering during the planing phase. Similar to the datafusion in datafusion setup we have right now, but balista in balista ;) Perhaps we could have a distributed version of Listing Table implementation in ballista in the future. -- This is an automated message from the Apache Git Service.
