I suggest u test out CouchBase or Cloudant or CouchDB as well. Riak can be problematic when things go wrong. On Thu, Jan 14, 2016 at 4:07 PM, Russell Brown wrote: > > > On 14 Jan 2016, at 07:05, j.halif...@seznam.cz wrote: > > Hi All, > > > I am a member of the community for about a year to unde

That’s right! No one ever had a problem with those products. Fact is riak has been described as “boring” and “like plumbing” and “we forget it’s there” by numerous customers. It is so reliable the UK health service selected us and had the most uptime they’ve _ever_ had since. The danish health

Given the tunables that Riak has, I would say that its reliability in terms of consistency (as in ACID) are unparalleled. It offers a variety of weak consistency options from eventual consistency, to strong eventual consistency, to strong consistency*. In terms of fault-tolerance, it is interestin

Hi All, Thank you for your kind info. Couldn't it be so that the paid version  of Riak is more reliable than the free one? Aren't the UK and Danish Governments using the commercial versions  of Riak? Thank you.. jh ___ riak-users

The paid version has multi-datacenter replication, so yes, more reliable in that you can lose a datacenter and stay available. The OS riak is in no-way crippled on unreliable, it just doesn’t have MDC replication. Another huge benefit of paying is access to our support team, who are frankly ama

Hi John, I tested Multipart Upload with aws-sdk-js with the patch you mentioned, against riak_cs (s2), upload finished without errors up to 1GB object. The environment is all local on my laptop, so latency is small. The script I used is in [1]. As Luke mentioned, HAProxy would be the point to be

Shino and Luke, Thank you for helping me work through this. The tcplog mode in haproxy actually doesn’t provide enough information because it doesn’t bother with paths or query strings or anything http like. I am using the httplog mode as a result, and the odd thing is that the error logged ind

2016-01-14 Thread Luke Bakken
Hi Zuzana, A good place to start would be to look for errors in Riak's log/error.log file. If you can run "riak-debug" on a crashed node and share the generated file, that would be helpful in diagnosis. I am assuming that your Java application and RabbitMQ server do *not* run on the same servers

I (think I) figured it out! I noticed while dumping some information out to the console, that when I uploaded to AWS I was seeing the Etag in the data passed to the callback for ManagedUpload.send(), but there was no Etag when I made the same request to RiakS2. This happened whether the file was
