Teiid 7.6 Beta1 发布,数据虚拟化平台
时间:2011-10-29 来源:红薯
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。
