Review Comment:
> Execution of query like:
SELECT ... WHERE ts BETWEEN 1078016000 and 1718953003 ...
will pass an empty result even with passed partition paths as UTF8Strings,
because we need to deal with initial UNIX_TIMESTAMP values for this filtering.
> Need to think about how to make it work.
It looks like there is no good way to fix this because of the datetime
string format, either we handle the partition paths from the query predicates
with the same key generator and use that for pruning or we store the initial
non-formatted partition values.
