  • First HBase meetup. Hosted by rapleaf -- 2007/12/18

  • Extensive refactoring of locking and addition of first version of a REST interface -- 2007/11/25

  • Cluster behavior has been much improved. The master, rather than the splitting region server host, now rules where the child splits are deployed. A simple formula has been added to spread region load evenly. Splits have been made near-instantaneous and compaction has been reworked so neither block updates for extended periods of time. -- Added 2007/08/16

  • Support for row and filter columns.
  • A simple shell for manipulating HBase tables contributed by Edward Yoon. -- Added 2007/07/10

  • Map/Reduce connector for HBase - contributed by Vuk Ercegovac -- Added 2007/06/30

  • Scripts to start and stop a hbase cluster have been added. See ${HBASE_HOME}/bin. List cluster participants in ${HBASE_HOME}/conf/regionservers file). -- Added 2007/06/21

  • A script to run distributed clients executing the Performance Evaluation tests described in the Google Bigtable paper has been added and tested to completion running against a small cluster of 4 region servers. See Tools for evaluating HBase performance and scalability -- Added 2007/06/21

  • It is now possible to add or delete column families after a table exists. Before either of these operations the table being updated must be taken off-line (disabled) -- Added 2007/05/30

  • Data compression is available on a per-column family basis. -- Added 2007/05/30 The options are:

    • no compression
