| Apache Tajo (incubation) |
| ======================== |
| Tajo is a relational and distributed data warehouse system for Hadoop. |
| Tajo is designed for low-latency and scalable ad-hoc queries, online |
| aggregation and ETL on large-data sets by leveraging advanced database |
| techniques. It supports SQL standards. It has its own query engine which |
| allows direct control of distributed execution and data flow. As a result, |
| Tajo has a variety of query evaluation strategies and more optimization |
| opportunities. In addition, Tajo will have a native columnar execution and |
| and its optimizer. |

| Disclaimer |
| ========== |
| Apache Tajo is an effort undergoing incubation at The Apache Software |
| Foundation (ASF) sponsored by the Apache Incubator PMC. Incubation is required |
| of all newly accepted projects until a further review indicates that the |
| infrastructure, communications, and decision making process have stabilized in |
| a manner consistent with other successful ASF projects. While incubation status |
| is not necessarily a reflection of the completeness or stability of the code, |
| it does indicate that the project has yet to be fully endorsed by the ASF. |
