Current status

Targeted release: Fedora 18
Last updated: 2012-08-20
Percentage of completion: 100%

Detailed Description

Fedora not only catches up recently with the other distributions in terms of available NoSQL databases and related software but overtakes almost all of them. Another one missing title is Riak.

Riak is a Dynamo-inspired key/value store, written in Erlang, that scales predictably and easily. Riak also simplifies development by giving developers the ability to quickly prototype, test, and deploy their applications.

A truly fault-tolerant system, Riak has no single point of failure. No machines are special or central in Riak, so developers and operations professionals can decide exactly how fault-tolerant they want and need their applications to be.

Benefit to Fedora

The installation procedure for Riak is quite complex. You need to grab sources from Git and install (in a specific order) about a dozen of packages each of them has their own set of dependencies which are also need to be resolved. AFAIK no other mainstream distribution provides the packages for Riak, so Fedora again will be the first one, who will enable simple installation of this NoSQL db. This in turn may attract people who still undecided which distribution whey should use.

(Note: From my internet-searching it does appear like it is available in other distros; we might want to revisit this section. --Rbergero (talk) 10:02, 18 September 2012 (UTC))

Scope

Some work was already done. However there is a lot of things to do:

How To Test

These simple examples must work as described after successful installation of Riak:

I'll provide more examples later.

User Experience

Users will be able to install Riak with only "sudo yum install riak" instead of reading large manuals, fetching sources from GitHub, compiling them, installing and fixing inevitable installation errors.

Dependencies

Adding riak doesn't break any already existing packages. It just adds several new ones. See the table above for the full list of dependencies and the current status.

Contingency Plan

None necessary.
