Basho and Gemini Mobile New Contributions to Erlang Cluster Management

After riak_core — the refactored Riak core that can be used for building distributed apps without shared state, Basho is releasing now riak_err:

The riak_err OTP application replaces about 90% of the default Erlang/OTP info/error/warning event handling mechanism. The replacement handler places strict limits on the maximum size of a formatted message. So, if you want to limit the maximum length of an error message to 64 kilobytes, you can. The result is that it’s now much more difficult to get Riak to crash due to error message handling.

riak_err is available on ☞ GitHub.

Gemini Mobile Technologies, the company behind Hibari, the distributed, high available key-value store, is open sourcing under Apache license cluster_info:

It provides a flexible and easily-extendible way to dump the state of a cluster of Erlang nodes. The app can also automatically gather all of this data from all nodes and write it into a single file. It’s about as easy as can be to take a snapshot of all nodes in a cluster.

Currently, cluster_info is packaged together with Hibari, but Basho will start distributing it with the next Riak release.

Hibari: Distributed, Fault Tolerant, Highly Available Key-Value Store

Two hours of Hibari, the key-value store from Japan we’ve first heard about back in July

By the way, Hibari is the first that filled its profile on the NoSQL reference card.

Google BigTable Paper Summarized

The slides below summarizing the Google BigTable paper are the result of a NOSQLSummer meeting in Tokyo. Nice!

Update: I just realized that the company that hosted this meeting, Gemini Mobile Technologies, is the same that announced yesterday the new key-value store Hibari

Hibari Cloud Database: A New Key-Value Store

Not sure we needed another key-value store, but it looks like we might get another one from Gemini Mobile Technologies:

Hibari Cloud Database is a distributed non-relational database management system (Distributed Non-RDBMS) for cloud computing to support explosively growing data volume.


While listing a tar.gz download, the ☞ sourceforge project page also mentions:

Hibari is a distributed, high availability key-value data store that focuses on the “C”onsistency and “A”vailability aspects of Brewer’s CAP Theorem.
