5 月 7 日,IBM 宣布为 IBM® DB2® Analytics Accelerator 这款广受欢迎的产品扩展功能,同时还提供了一套临时修复程序 (PTF) 及大量文档更改。这些更改将于五月和六月期间与用户见面,其中新增了多项预期功能,如降低数据延迟,以及将产品存储容量扩展到超过 1.2 TB。下文将概括介绍这些新功能,同时我们会在下一版产品中对它们进行进一步增强。
增量更新
全新的增量更新功能可通过读取 IBM DB2 for z/OS® 上的日志并将这些更新应用至 DB2 分析加速器,从而全天候持续更新 DB2 分析加速器内的表。启用此功能后,查询任务将进入以近实时版本数据为基础运行的 DB2 分析加速器。此功能可防止客户为当前版本的加速器重新加载数据。当加速工作负载要求使用最新版本的 DB2 数据时,企业即可使用增量更新功能。虽然很多情况下仍然需要执行全面刷新及基于分区的刷新,但增量更新不能取代刷新流程,它只是对刷新功能进行了增强。

高容量
支持范围扩大,可涵盖整个 IBM Netezza® 1000 数据仓库设备产品系列。DB2 分析加速器现已从 1/4 尺寸机箱扩大到 10 机箱 Netezza 1000 设备。这种转变表明客户需要大型加速器以满足搭配使用高容量数据仓库与 IBM System z® 的需求。DB2 Analytics Accelerator V2 于 2011 年 10 月首次发布,它支持 1/4、1/2 或全尺寸机箱,从而将加速器限制在 96 处理器,且有效存储为 128 TB。然而,具备充分扩展功能后,客户可以充分利用从 24 处理器(具有 32 TB 有效存储)到 960 处理器(具有 1,280 TB 有效存储)的处理器。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
