Implementing and evaluating an anti-entropy protocol for riak_core_lite

[bieniusa]

Description
Active anti-entropy (AAE) identifies and repairs data inconsistencies between a system's replicas. It is typically implemented as a set of background processes that iterate over the data items, compare their state and trigger synchronisation actions.
Riak_core_lite currently does not offer an active anti-entropy module.

Recommended Skills

• Good programming skills in Erlang
• Basic knowledge about distributed systems

Mentor(s)
Albert Schimpf, Mariano Guerra, Annette Bieniusa

Project URL(s)

• https://riak-core-lite.github.io
• Information on AAE in riak: https://docs.riak.com/riak/kv/2.2.3/learn/concepts/active-anti-entropy/index.html

@bieniusa @marianoguerra @albsch is this something you still want to do this year?

[bieniusa]

We are happy to offer it again this year.

[pablocostass]

Woohoo! Those are great news :)

@bieniusa @marianoguerra @albsch (sorry for the ping yet again) so it seems that for this year's edition we have to add the following information to the project, would you be so kind to get back to me with it?

• expected outcome
• expected size of project (175 or 350 hour)
• an easy, medium or hard difficulty rating the project

[bieniusa]

Sorry for the delay...

Expected outcome:

• extended/modified vnode behavior that implements AE
• user documentation on AE
• test cases cases that fail with the current riak_core implementation but succeed with AE

Expected size: both possible, we would target 175h

Difficulty: medium / hard

No probs for the delay, life happens :)

I have updated your project description on the wiki, thank you Annette!
