<s>[INST] I have a big tempDB with plenty of data in it. I know that the date is causing the size of the tempDB to grow.

I'm resolving that I will invest some time to clean up each table and bring the size down if it is too large. But I'd also want to bring down malloc memory used cache for the tempDB.

How can I empty out the objects without losing data and bring down the malloc memory?[/INST]
