| Apache Tajo™: A big data warehouse system on Hadoop |
| |
| 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. |
| |
| Features |
| |
| * <<Fast and Efficient>> |
| |
| * Fully distributed SQL query processing engine |
| |
| * Advanced query optimization such as cost-based and progressive query optimization |
| |
| * Interactive analysis on reasonable data set |
| |
| * <<Scalable>> |
| |
| * Fault tolerance and dynamic scheduling for long-running queries |
| |
| * Out-of-core algorithms for data sets larger than main memory |
| |
| * <<Compatible>> |
| |
| * ANSI/ISO SQL standard compliance |
| |
| * Hive MetaStore access support |
| |
| * JDBC driver support |
| |
| * Various file formats support, such as CSV, JSON, RCFile, SequenceFile, ORC and Parquet |
| |
| * <<Easy>> |
| |
| * User-defined functions |
| |
| * Interactive shell |
| |
| * Convenient Backup/Restore utility |
| |
| * Asynchronous/Synchronous Java API |
