Re: Continuous HTTP POSTs to Riak

[Christopher Mancini]

If you don't need strong consistency for all Riak requests, just certain
ones, then explore the use of R and N vals that can be passed along with
the request or on a bucket-type level.

Re: Ok, I am stumped. Losing data or riak stop

[Christopher Mancini]

Hey Joe,

I will do my best to help, but I am not the most experienced with Riak
operations. Your best bet to get to a solution as fast as possible is to
include the full users group, which I have added to the recipients of this
message.

1. Are the Riak data directories within Vagrant shared directories between
the host and guest? I have had issues with OS file system caching before
when working with web server files.

2. What version of Ubuntu are you using?

3. How did you install Riak on Ubuntu?

4. Have you tried restoring the original distribution riak.conf file and
seen if the issue persists? This would help you determine if the issue is
your config or something with your environment.

Re: Testing On A Single Node

[Christopher Mancini]

To second Vitaly, losing data in restart is not normal. What OS are you
running it on? Is it in a VM or on bare metal? How did you install it? Did
you change any riak.conf vars? With this info, we should be able to help
you trouble shoot this issue better.

Riak PHP Client v3 and official Protocol Buffers support v1

[Christopher Mancini]

This week we released a significant update to the PHP client to support API
bridge classes other than the Http class that ships with the client
library. This work was released as version 3 due to a few minor interface
changes that break backwards compatibility. Those breaking changes are:

   - Basho\Riak\Command\Object\Response::getVclock() has been moved to
   Basho\Riak\Object
   - Basho\Riak\Command\Object\Response::getStatusCode() has been
   renamed Basho\Riak\Command\Object\Response::getCode()
   - Basho\Riak\Command\Object\Response::getBody() has been removed

We also released official support for Protocol Buffers using PHP. This
support is delivered via an independent package that has the core library
above included as a dependency. This allows us to keep the same programming
interface while keeping the dependencies needed for PB separate from those
needed by HTTP.

Both releases can be retrieved from packagist.com @
https://packagist.org/packages/basho/

Enjoy!

Re: Using Bucket Data Types slowed insert performance

Re: Using Bucket Data Types slowed insert performance

[Christopher Mancini]

Hi Dennis,

I am not the most experienced, but what I do know is that a file that size
causes a great deal of network chatter because it has to handoff that data
to the other nodes in the network and will cause delays in Riak's ability
to send and confirm consistency across the ring. Typically we recommend
that you try to structure your objects to around 1mb or less to ensure
consistent performance. That max object size can vary of course based on
your network / server specs and configuration.

I hope this helps.

Re: Riak C example segmentation fault

[Christopher Mancini]

Hi Tom,

Unfortunately, I believe the C client was a project that was started with
the intention of knocking down two birds with one stone, official support
for C and wrap it as a C extension for PHP. The project has not been
updated in about a year, while other clients have seen a lot of updates in
that time.

I'm aware that we do not have any Basho resources towards moving this
client forward in the near future, which leaves me with essentially three
options: 1) Submit GH issues for each problem you encounter we can try to
queue up time to review them. 2) Submit contributions to the project by
fixing the issues and submitting a PR for each fix. 3) If time is of the
essence, consider using one of our officially supported clients [1] or this
C client that seems to have some recent momentum [2]

[1] http://docs.basho.com/riak/latest/dev/using/libraries/
[2] https://github.com/algernon/riack

I hope this helps.

Re: Bug: Stanchion 1.5 in repo along riak cs 2.0

[Christopher Mancini]

Kota,

I think Toby is right, if you look at packagecloud.io, there is no
reference to stanchion 2, only 1.5.

https://packagecloud.io/basho/riak-cs?filter=debs

Not sure who can fix this, but its certainly not aligned with our
recommendations.

Re: Ansible galaxy roles only support three-year-old Ubuntu 12.04

[Christopher Mancini]

Hi Toby,

I am actually working on a rewrite of the Galaxy role that we used to have
up there to be simpler and support all of the 2.x features of Riak. You can
access it here: https://github.com/basho-labs/ansible-riak/tree/dev-2.x

I would greatly appreciate any feedback, suggestions as well as any
contributions you may have from your testing on Ubuntu / Debian, since I am
using it with CentOS7 and may not have time to test it with Ubuntu for a
little while still.

Chris

Re: Looking for a sample to store and retrieve images in Riak using UGameDB

[Christopher Mancini]

Hey Syed,

I don't have an example to provide but I am assuming you could store the
image in Riak using the Bitstream encoding offered by the uGameDB lib.
Alternatively, you could probably parse the image as a binary string,
escape it and then store it within a json object using json encoding.

Here are two links with this info:
http://developer.muchdifferent.com/unitypark/uGameDB/SerializationMethods
http://developer.muchdifferent.com/unitypark/uLink/Serialization
http://www.tutorialspoint.com/csharp/csharp_data_types.htm

Hope this helps you.

PHP Client Release

[Christopher Mancini]

Greetings Riak Users!

Yesterday we released the awaited rewrite for the Official PHP client for Riak 
supporting version 2 features (bucket types, CRDTs, and user authentication 
over TLS). The library uses the HTTP interface to communicate with Riak and 
requires PHP version 5.4 or newer as well as the JSON and cURL PHP extensions.

It's available via composer:

https://packagist.org/packages/basho/riak 
<https://packagist.org/packages/basho/riak>

Simply add the following to your composer.json file within your project:

 "require": { "basho/riak": "2.0.*" },

The github repo can be found here:

https://github.com/basho/riak-php-client 
<https://github.com/basho/riak-php-client>

API docs are published here:

http://basho.github.io/riak-php-client/ 
<http://basho.github.io/riak-php-client/>

Thanks,
Christopher Mancini
