Teiid 8.8 正式版发布了，该版本值得关注的改进有：
- TEIID-2647 Translator for Cloudera's Impala data warehouse has been added. See the reference for more.
- TEIID-2902 More incremental joins where the whole dataset does not need fully sorted or even read.
- TEIID-2263 More control over MAKE (NOT) DEP hints via syntax that allows for traversing views. See the reference for more.
- TEIID-2263 Common Table (WITH) planning improvements such that the usage of a WITH clause in a view or inline view no longer inhibits planning as part of the larger query.
- TEIID-2980 XMLTable Array Support - XMLTABLE may now return arrays for sequence values.
- TEIID-1675 Updatable LDAP multi-valued attributes - using an array type mapping, LDAP multi-valued attributes can be inserted/updated.
- TEIID-3018 System tables for view/procedure definitions - the SYSADMIN Views and StoredProcedures tables can be used to access the definitions of the views/procedures.
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。
