New port: apache hbase:

Apache HBase is an open-source, distributed, versioned, non-relational database
modeled after Google's Bigtable: A Distributed Storage System for Structured
Data by Chang et al.  Just as Bigtable leverages the distributed data storage
provided by the Google File System, Apache HBase provides Bigtable-like
capabilities on top of Hadoop and HDFS.
