It supports SQL standards. It has its own query engine which\nallows direct control of distributed execution and data flow. As a result,\nTajo has a variety of query evaluation strategies and more optimization\nopportunities. In addition, Tajo will have a native columnar execution and\nand its optimizer.\n\n## Project\n\n* [Project Home](http://tajo.apache.org/)\n* [Source Repository](https://github.com/apache/tajo.git)\n* [Issue Tracking](https://issues.apache.org/jira/browse/TAJO)\n\n## License\n\n* [Apache License 2.0](http://www.apache.org/licenses/LICENSE-2.0.html)\n\n## Documents\n\n* [Tajo Wiki](https://cwiki.apache.org/confluence/display/TAJO)\n* [Getting Started](http://tajo.apache.org/docs/current/getting_started.html)\n* [Query Language](http://tajo.apache.org/docs/current/sql_language.html)\n* [Configuration Guide](http://tajo.apache.org/docs/current/configuration.html)\n* [Backup and Restore Guide](http://tajo.apache.org/docs/current/backup_and_restore.html)\n* [Functions](http://tajo.apache.org/docs/current/functions.html)\n* [Tajo Interactive Shell](http://tajo.apache.org/docs/current/tsql.html)\n\n## Requirements\n\n* Java 1.8 or higher\n* Hadoop 2.3.0 or higher\n\n## Mailing lists\n\n* dev@tajo.apache.org     - To discuss and ask general development issues.\n* user@tajo.apache.org    - To discuss and ask end-user questions/issues.\n* issues@tajo.apache.org  - To see notifications made in the Tajo issue\n                            tracking system, review board, and Jenkins CI.\n* commits@tajo.apache.org - To monitor commits to the source repository.\n\nTo subscribe to the mailing lists, please send an email to:\n\n    ${listname}-subscribe@tajo.apache.org\n\nFor example, to subscribe to dev, send an email from your desired subscription address to:\n\n    dev-subscribe@tajo.apache.org\n\nand follow the instructions from there.","funding_links":[],"categories":["Java","java","大数据"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Ftajo","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fapache%2Ftajo","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fapache%2Ftajo/lists"}
