Importance of distributed locking
Locking is one of the most important synchronization techniques in a database. It is a must
if multiple users are interacting with it simultaneously. The use of a high-level API (along
with a version attribute in the mapping class) ensures locking. In the case of a multiuser,
multiserver database environment, if distributed locking is not incorporated then most of
the users may well be sitting on the detached branch of the tree and working on obsolete
data. The importance is actually in deciding whether we need this locking, because as a
tradeoff every item will have an attribute especially to manage versions or locking, which
might itself eat up a lot of space and throughput capacity.
