Hi,
I'd like to know how works Riak when my bucket has n_val = 3 and only 2
physical nodes.
Does Riak make 3 copies of the bucket over the 2 nodes or it maintains
only 2 copies of my bucket on the cluster ?
I'm doing tests of riak and i find some things weird.
I have a two nodes cluster and a bucket with n_val = 3.
I put more than 1 600 000 documents in the bucket and it takes less than
200 GB with Innostore.
I shut down the second node with "q()." in a "riak console".
Firstly, there was no synchronisation of data on the first node, i
assume it's better because very similar to a node crash.
Secondly, when i did a read request on a document with :
- ?r=1 -> success
- ?r=2 -> success
- ?r=3 -> fail
An other question, "n replicas" means "1 + n copies" or "n copies" of
the bucket ?
I really appreciate if you can explain me this behavior ?
Thank you
Best Regards,
