Is there a practical (or hard) limit to the number of buckets a riak cluster
can handle? One possible data model we could use for one application could
result in ~80,000 buckets. Is that a reasonable number?
Thanks,

Scott,
There is no limit on the number of buckets unless you are changing the bucket
properties, like the replication factor, allow_mult, or the pre- and
post-commit hooks. Buckets that have properties other than the defaults
consume space in the ring state. Other than that, they are essentia
There is no limit to the amount of buckets a cluster can handle. The
only consideration I know of is when using non default bucket
properties (like bucket specific N vals). The reason being that non
default values are chatted around the cluster in the gossip channel.

Thanks for the quick replies Sean and Alexander. One of our current
products allows users to sign up for weather alerts based on their zip
code. When we receive a weather alert for a set of locations, we need
to quickly find all users in the zip codes effected. We currently do
this with a sim
Listing keys in a bucket is not necessarily going to be faster than storing the
list in an object. You might want to measure this to be sure - be aware that
list-keys is bound by the total number of keys in the cluster, not by the
amount in the bucket.

Over the last few weeks I've been finding it harder and harder to start
riak which given that it's running on an auto-provisioned ec2 instance is
a bit of an issue! I can generally restart it by running
/etc/init.d/riak restart but it's got to the stage where I have to run
it four or five times. I

I think the slowness is coming from the older list keys implementation in
0.12.1, list keys has been changed in the tip version of Riak and is quite a
bit faster now. In addition there have been a lot of improvements to the
Javascript map reduce implementation that should help the speed of your
Hey guys I have an application using Riak 0.12 that does puts, gets, and
updates. It works fine but I get these random error reports in my logs.
Any ideas?

Hi Michael,
These errors are almost certainly harmless and being thrown when empty,
non-owned vnodes get shut down.
It appears that in some cases, the underlying ets table might already be
deleted/GC'd by the time BackendModule:stop tries to explicitly delete it.

Hi Scott,
Until Riak gains the ability to constrain list traversals by bucket this will
continue to be a point of friction. This issue has been broached before and
there are tickets open on the issues tracking site. As I understand it, one
solution would potentially modify bitcask to open a 'ca
