PKCondition: infer index use with pk subexpression
...
By default only constraints explicitly matching
primary key expression (or expression wrapped in
a monotonic function) are eligible for part and
range selection. So for example, if index is:
(toStartOfHour(dt), UserID)
Then a query such as this resorts to full scan:
SELECT count() FROM t WHERE dt = now()
Intuitively, only parts with toStartOfHour(now())
could be selected, but it is less trivial to prove.
The primary key currently can be wrapped in a chain
of monotonic functions, so following would work:
toStartOfHour(dt) = toStartOfHour(now()) AND dt = now()
It must be however explicitly stated, if we wanted
to infer that we’d have to know the inverse function,
and prove that the inverse function is monotonic
on given interval. This is not practical as
there is no inverse function that for example undos
rounding, it isn’t strictly monotonic.
There are however functions that don’t transform
output range and preserve monotonicity on the
complete input range, such as rounding or casts
to a same or wider numeric type. This eliminates
the need to find inverse function, as no check for monotonicity over arbitrary interval is needed,
and thus makes this optimisation possible.

Dictionaries/TrieDictionary: IP prefix dictionary
...
This commit implements a basic IP prefix dictionary
that allows storing IPv4/IPv6 prefixes and
matching them against a single IP address on query
time. This allows for doing IP -> ASN matching and
other similar things on query time.
The implementation is basic for start, using a
simple bitwise trie and reusing interface for
complex key dictionaries (so using tuple instead
of UInt32/FixedString(16) as the key). A faster
bitwise trie implementation (like poptrie) is
desired to improve lookup performance and
memory consumption with large prefix tables.
