Teiid 8.9 Final 发布，此版本的开发比往常的 12 个星期多了 4 个星期，主要是要适应一个新版本的 host 环境 JBoss EAP 6.3.0 Alpha。此版本现已提供下载：http://teiid.jboss.org/downloads/ 。
此版本解决了超过 100 个 issues，主要改进内容如下：
•TEIID-3009 WITH project minimization - common table expressions will have their project columns minimized.
•TEIID-3038 geoSpatial support for MongoDB translator
•TEIID-3050 Increased Insert Performance with sources that support batching or insert with iterator.
•TEIID-3044 Function Metadata is available through system tables and DatabaseMetaData.
•TEIID-1910 TeiidPlatform for EclipseLink integration is now provided via the teiid-eclipselink-platform jar in maven.
•TEIID-3119 Performance improvements in grouping and duplicate removal as well as general improvements to memory management.
•TEIID-3156 Collation aware prevention of order by pushdown via the collationLocale translator property and the org.teiid.requireTeiidCollation system property.
•TEIID-3042 Usage Information on views and procedures in the system table SYSADMIN.Usage.
•OData4 Support - There is partial support for OData4 using the Apache Olingo project. The OData2 is still intact. We consider this still as experimental feature.
Teiid 8.10 的开发正在进行中，计划在 2015 年 2 月 15 日发布。
Thank you.

Teiid是一个数据虚拟化系统，让应用程序使用来自多个异构数据存储的数据。
Teiid由一堆工具，组件和创建和执行双向数据的服务所组成。通过抽象和联合、数据存取和集成的实时分布式数据源，无需进行复制或以其他方式移动数据系统的纪录。
简而言之：Teiid 可以让你用 JDBC + SQL 来访问企业的任何数据，并可对这些不同源的数据进行联合查询。
