CQL will have UPDATE future, I am trying to understand how this could work.
Every write is an append to SSTable, UPDATE would need to change data, but
only if it exists, and this is problematic, since we have distributed
system.
Is UPDATE special kind of insert, which changes given data only if
In CQL, both UPDATE AND INSERT have the same semantic and are both upsert.
I.e, INSERT does not fail if the record was already existing and
UPDATE does not fail if the record wasn't existing.
