Teiid 7.6 Beta1 发布，数据虚拟化平台

7.6 Beta1 发布了，该版本在内存管理方面做了很多改进，包括：

• 修正的内存缓冲区 - A serialization buffer will be allocated to increase disk through-put. It is also managed as a second tier cache. You may optionally configure the size and set it to use off-heap memory - which is especially useful for dealing with larger amounts (typically 32BG+) of memory from the VM. The memory buffer also allows for better disk usage based upon fixed allocation blocks vs. the old Teiid scheme which used a file per table/tuple buffer.
• 并发 LRFU - the main eviction algorithm was further refined to be concurrent and to better handle table work loads.
• 许多性能的提升 - batch size estimation, serialization, and value type resolution were all improved.

另外你还可以配置默认的查询超时时间，包括服务器端和 VDB。

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。
