> It would be handy to be able to pass in a list of fully qualified composite partition keys in an IN filter to retrieve multiple distinct rows with a single select. Not entirely sure how that would work. It looks like maybe it could be done with the existing token() function, like:
> SELECT * FROM table WHERE token(keyPartA, keyPartB) IN (token(1, 1), token(4, 2))
> Though, I guess you'd also want some way to pass a list of tokens to a prepared statement through the driver. This of course all assumes that an IN filter could be faster than a bunch of prepared statements, which might not be true.
