Cloudata: A New Open Source BigTable Inspired Database

Cloudata is a new open source implementation of Google’s BigTable paper. It can be found on Github here. It appears to be the project of a Korean developer named YKKwon.

As noted at MyNoSQL, there are only a couple commits and it’s not clear how serious this project is. But it will be of interest to big data, MapReduce and BigTable buffs.

Cloudata differentiates itself from Hadoop by offering an indexed but still non-relational database, but is probably more comporable to HBase and Hypertable, which are also open source BigTable implementations. The project’s website claims Cloudata can retrieve data within a few milliseconds.

Here’s a list of the current features:
