Atomicity is always a delicate subject, but it could be resolved with
either the following solutions:
1. Your application can have a re-entrant or synchronized lock:
/lock(username) { create if not present then exit lock; if present
then return to user asking for another username }/
2. Or
Chiming in on this as well -
Using lock(username) will work as long as you have a centralized
application server where all creates occur. As soon as you have two systems
involved you can run into the same problems that you'd run into with Riak.
Issuing a lock is, however, a great way to get starte
Thanks, this is all very helpful.
I think what I'll do is keep the Riak settings at default and not do
anything tricky there.
And then I'll use Redis as a locking manager as described here:

Initially it will just be a single Redis instance but by the time I'm rea

There's no way to specifically delete a bucket - buckets are, in part, a
logical namespace. Once you delete every key in a bucket the bucket will
effectively be deleted. The easiest thing to do in a test environment is to
run list keys on the bucket. This is a terrible idea for a production
system
Hi All,
I would like to know the data storage of my riak database till date.
Also, I would like to know the space occupied on a riak cluster by a
bucket/key's data inserted. am running all the nodes(in the cluster) on
eleveldb backend.
Thanks,
Venkatesh
