#cloudata

Cloudata is the third open source implementation of Google’s BigTable paper, after HBase and Hypertable[1]. There’s already an 1.0 version even if the Github project page is listing just a couple of commits.

From the home page, Cloudata’s current features:

Basic data service

Single row operation(get, put)

Multi row operation(like, between, scanner)

Data uploader(DirectUploader)

MapReduce(TabletInputFormat)

Simple cloudata query and supports JDBC driver

Table Management

split

distribution

compaction

Utility

Web based Monitor

CLI Shell

Failover

Master failover

TabletServer failover

Change log Server

Reliable fast appendable change log server

Support language

Java, RESTful API, Thrift

I couldn’t figure out if this is just an experiment or if it actually plans to be a real project.

Update: Cloudata's author, Jsjangg, mentions in the comment thread that Cloudata is used at www.searcus.com for 2 years already running on a 20 machine cluster.

See why I haven't included Cassandra in this list in the comment thread.  ↩
