> This changes the drop partition operation to asynchronous. The data files of transactional tables will not be deleted, but a new truncated basefile will be written, which is going to be later cleaned up by the Compactor/Cleaner.
> This along with a few other changes will enable us to not use read locks, which provides perf boost to the transactional tables.
