New Meetup: Hibari - distributed, fault tolerant, highly available key-value store

From: Martin J. L.
Sent on: Tuesday, August 10, 2010 5:09 PM
Announcing a new Meetup for Chicago Erlang User Group!

What: Hibari - distributed, fault tolerant, highly available key-value store

When: Wednesday, August 25,[masked]:00 PM

Where: Orbitz
500 West Madison Street
Chicago, IL 60661

Hibari is a distributed, fault tolerant, highly available key-value
store written in Erlang. Data replicas are managed by chain replication
rather than the more common quorum voting technique used by Riak,
Cassandra, and others. Hibari supports micro-transactions (atomic
updates to multiple keys in limited circumstances) and cluster resizing
(both growing and shrinking the cluster). Hibari clients can be written
in Erlang as well as C, C++, Java, Python via the UBF protocol and soon
in other languages via Protocol Buffers and Thrift.

Hibari was released to the open source community under an Apache License
v.2.0 and is available at Hibari's
largest commercial deployment is a Webmail system in Asia that is
managing approximately one billion email messages.

My talk in Chicago will be the Hibari's first public presentation. I'll
talk about its major features, how chain replication works, and how
Hibari's sponsor (Gemini Mobile Technologies) will manage code patches
from the open source world. I'll leave the rest to audience questions,
with just-in-case material for demo'ing things like cluster
expansion/contraction and developing a small client application that
uses micro-transactions.
