How to clear table data quickly?

Hi community,

For some tables with a large amount of data, how to quickly clear the 
data in this table?

Hello!

You can do cache.clear() or you can drop and create table (or cache).

I'm not sure what will be faster. It depends, since the latter will cause a
Partition Map Exchange, while former will be executed entirely in
background.
