Apache Kylin 1.3.0 发布了,Kylin 是一个开源的分布式的 OLAP 分析引擎,来自 eBay 公司开发,基于 Hadoop 提供 SQL 接口和 OLAP 接口,支持 TB 到 PB 级别的数据量。

Kylin 是:

  • 超级快的 OLAP 引擎,具备可伸缩性

  • 为 Hadoop 提供 ANSI-SQL 接口

  • 交互式查询能力

  • MOLAP Cube

  • 可与其他 BI 工具无缝集成,如 Tableau,而 Microstrategy 和 Excel 将很快推出


  • 作业管理和监控

  • 压缩和编码的支持

  • Cube 的增量更新

  • Leverage HBase Coprocessor for query latency

  • Approximate Query Capability for distinct Count (HyperLogLog)

  • 易用的 Web 管理、构建、监控和查询 Cube 的接口

  • Security capability to set ACL at Cube/Project Level

  • 支持 LDAP 集成
