Upcoming Riak Version Getting Some New Cool Features
Firstly, after dropping their custom protocol Jiak, upcoming Riak version will support protobuf[1]. You’ll find some technical details about the Riak Protocol Buffers Client and API ☞ here.
Secondly, the new version of Riak will finally feature pre-commit and post-commit hooks[2]. These hooks can be defined on each per-bucket:
Pre-commit hooks are invoked before a riak_object is persisted. Pre-commit hooks can:
- allow the write to occur with an unmodified object
- modify the object
- Fail the update and prevent any modifications
Post-commit hooks are notified after the fact and should not modify the riak_object.
I guess we will have another exciting release from Riak[3] soon!
