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
  

其他值得关注的特性包括：

• 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
