# 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
* `rocksdb` backend - this version ships with a pluggable backend for the hashtree (aae and metadata) functionality, using either `leveldb` or `rocksdb`
* 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
[](http://travis-ci.org/basho/riak_core)
Riak Core is the distributed systems framework that forms the basis of
how [Riak](http://github.com/basho/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](http://basho.com/where-to-start-with-riak-core/)
that’s well worth your time.
