Hi Kaniz, I found the equivalent SQL code for this but it didn't seem to store the operation past the execution. I.e I would run the code to configure settings, then run the troublesome code afterwards and still get the same result. The problem has b...
Hi, I am wondering if multithreading will help with the performance for z-ordering optimization on multiple delta tables.We are periodically doing optimization on thousands of tables and it easily takes a few days to finish the job. So we are looking...
