Hi - I'd appreciate if someone can opine on the below behavior of Riak that
I am observing... is that expected, or something wrong in my set-up /
understanding?
To summarize, I have a 3-node Riak cluster (separate EC2 AWS instances)
with a separate chat server connecting to them. When I write data
ring?

I have a Riak cluster (of 3 nodes, with 64 partitions and n_val = 3) but I
find that for some objects, their hosting partitions / vnodes are not
spread out across the 3 nodes. In some cases, 2 of them are on 1 node and
the third is on a second node. That runs contrary to my understanding (link

Hi - I've been testing a Riak cluster (of 3 nodes) with an ejabberd
messaging cluster in front of it that writes data to the Riak nodes. Whilst
load testing the platform (by creating 0.5 million ejabberd users via
Tsung), I found that the Riak nodes suddenly crashed. My question is how do
we recove
you run with less memory.

Hi - I have a Riak node with n_val=3, r=2, w=2 and have just one key-object
stored there-in. I'm trying to test various configurations to better
understand the system and have the following observations - some dont seem
to align with my understanding so far, so appreciate if someone can throw
some

Hi - I am creating a messaging platform wherein am modeling each topic to
serve as a separate bucket. That means there can potentially be millions of
buckets, with each message from a user becoming a value on a distinct
timestamp key.
My question is there any downside to modeling my data in such a
that all buckets are part of that bucket type.

Hi - I am trying to leveraging CRDT sets to store chat messages that my
distributed Riak infrastructure would store. Given the intrinsic
conflict-resolution, I thought this might be more beneficial than me
putting together a merge implementation based on the causal context.
However, my data model
