Custom Object Mapper settings in Java Client

Hi I presume that Riak Java client is using Jackson for JSON-to-POJO and vice versa. Is there a way to easily inject a custom object mapper there? Or at least to get a reference to it in order to add custom serializers? Thank you Cosmin ___ riak-users

Re: AWS instance types

Both AWS engineers and Basho people, will most likely ask for throughput etc before recommending solutions. That being said, there’s a few things to consider. For example, most AWS engineers will suggest you use all the availability zones when deploying a distributed storage solution like Riak.

Re: Strong consistency only for missing keys?

Hi Ilya Read “quorum” is unusual and a bit against the idea of distributed DB, but I believe what you might find useful is enabling strong consistency, which you can then chose to apply at a bucket(type) level: * http://docs.basho.com/riak/latest/dev/advanced/strong-consistency/ One of the reas

Java Client and/or server error codes

I’m simulating a failure with a concurrent update on a strongly consistent bucket/entry. This fails as it should for the second update, however the error message/code is not entirely useful. com.basho.riak.client.core.netty.RiakResponseException: failed We’ve investigated this and the error

Riak Java Client

One quick question on the Riak Java Client. Brian Roach seemed to have been the only active contributor to this. Recently he mentioned that he's leaving Basho though, so I was wondering if he'll be maintaining this moving forward. Since the Riak Java client is now a fundamental part of our ec

Java Client update vs store

I have an edge case where consistency is favoured over availability so I’m using a "consistent": true bucket type for a very specific operation. I worked in testing my setup so ended up faking an entire failure by deliberately using an incorrect vClock. Using StoreValue, the (second) write fails

Riak Java Client and Links

I am implementing a custom way to handle Riak Links using a Java Client. Looking at the samples available (https://github.com/basho/riak-java-client/wiki/Using-links which is outdated) it seems that it’s not entirely straightforward to use RiakLinks with POJOs and automatic conversion. More imp

Re: Having trouble in connecting to Riak in EC2 with another Ec2 instance

Hi Santi, I’m presuming you’re running Linux, so this might be the result of Riak binding to 127.0.01 by default. You might want to adjust that in /etc/riak/riak.conf Check for listener.protobuf.* and listener.http.* area. More on this topic here: http://docs.basho.com/riak/latest/ops/building/b

Links and Bucket Types

Using Riak 2.0.2 on CentOS and trying to create some Links attached to an object using the Links header. We are using bucket types and this behaviour doesn’t seem to replicate when using plain buckets. Doing the following works as expected curl -H "Content-Type:text/plain" -X POST "http://19

Link Walking and Security

(Apologies if this is a recurring topic, but I haven’t read a clear statement yet in relation to this) Using Riak, I sometimes feel that link walking might be a corner stone for certain data modelling techniques. The Riak documentation though states clearly that this is not feasible while also

Java Client and clobber update

I’m doing a fairly “by the book” clobber update (store and fetch below work fine) on an entity using the Java client. I’m seeing an error that happens at type-inference time within the Riak Java client. I’m pasting below the exact test that I’m using to generate this, as well as the stacktrace.

Wiping Riak 2.0 data

Hi, I’m running Riak 2.0.2 on Centos 6.5 installed from an RPM (http://s3.amazonaws.com/downloads.basho.com/riak/2.0/2.0.2/rhel/6/riak-2.0.2-1.el6.x86_64.rpm) I’m interested in wiping the entire storage (in order to re-run tests, etc). I have a script that traverses buckets/keys but I’m aware
