Valkey is an advanced key-value store. It is similar to memcached but the dataset
is not volatile, and values can be strings, exactly like in memcached,
but also lists, sets, and ordered sets. All this data types can be manipulated
with atomic operations to push/pop elements, add/remove elements, perform server
side union, intersection, difference between sets, and so forth. It supports many
different kinds of sorting abilities.
