What is riak_core_ng?

The 'ng' version of riak core is a modernized version of riak core, it is entirely build with rebar3 using hex packages for all dependences, with more modern versions of some libraries. 99.9% of all credit goes to basho, very little extra work has happened here! The aim is to keep this up to date with all changes pushed to riak_core proper.

Improvements and Additions

  • R19 compatibility - This form works with R18 and R19 (lower versions should work but are not tested)
  • AAE - this version includes the Active Anti Entropy code extracted from riak_kv and provides a new behavior called riak_core_aae_vnode.

Riak Core

Build Status

Riak Core is the distributed systems framework that forms the basis of how Riak distributes data and scales. More generally, it can be thought of as a toolkit for building distributed, scalable, fault-tolerant applications.

For some introductory reading on Riak Core (that’s not pure code), there’s an old but still valuable blog post on the Basho Blog that’s well worth your time.
