Apache Trafodion is an open-source project is currently incubating at the Apache Software Foundation and was originally developed by the IT division of Hewlett-Packard Company and HP Labs to provide an enterprise-class transactional SQL-on-HBase solution targeting big data transactional or operational workloads.[1] The project is named after the Welsh word for transactions.[1]
Features
Trafodion is a database management system that runs on top of Hadoop,[2] providing support for transactional or operational workloads in a big data environment.[1] The following is a list of key features:
- ANSI SQL language support[2]
- JDBC and ODBC connectivity for Linux and Windows clients[2]
- Distributed ACID transaction protection across multiple statements, tables, and rows[2]
- Compile-time and run-time optimizations for real-time operational workloads[2]
- Support for large data sets using a parallel-aware query optimizer and a parallel data-flow execution engine[2]
Transaction management features include:
- Begin, commit, and rollback work syntax, including SET TRANSACTION[2]
- READ COMMITTED transactional isolation level[2]
- Multiple SQL processes participating in the same transaction concurrently[2]
- Recovery after region server, transaction manager, or node failure[2]
- Support for region splits and balancing[2]
History
Trafodion was launched by HP as an open-source project on June 10, 2014.[3]
A production ready version of Trafodion was released on January 29, 2015.[4]
