Apache Tajo is a robust big data relational and distributed data warehouse system for Apache Hadoop. Tajo is designed for low-latency and scalable ad-hoc queries, online aggregation, and ETL (extract-transform-load process) on large-data sets stored on HDFS (Hadoop Distributed File System) and other data sources. By supporting SQL standards and leveraging advanced database techniques, Tajo allows direct control of distributed execution and data flow across a variety of query evaluation strategies and optimization opportunities. Board Issues ============= There are no outstanding issues requiring board attention. Current Activity ================ Recently, we are discussing 0.9.1 release (incremental release), including bug fixes and new features, such as HBase storage support, recap of timezone, and Hadoop dependency removal from TajoClient. For 0.9.1 release, we have resolved about 80 issues since last release in Oct 2014. Releases =============== - Apache Tajo 0.9.0 (major release) (October 21, 2014) - Apache Tajo 0.8.0 (major release) (May 1, 2014) The last committers or PMC members elected =========================================== Last new PMC member: Hyoung Jun Kim <hjkim@apache.org> on 2014/12/08 Last new committer: Hyoung Jun Kim <hjkim@apache.org> on 2014/08/06
