Does this support JOINs? Or do you use a giant WHERE IN () clause?
My use case is essentially a cross-database JOIN that I've been using MySQL & temp tables to accomplish. For example, give me the sum of column x if column y is any one of these 50,000 values from a separate system. So load the 50,000 values into a temp table and then do a JOIN. Performance isn't that great and it uses a ton of disk space so I wanted to try using a columnar store.
