南大通用GBase 8s数据库通过其内存数据仓库加速器（IWA）技术，为企业提供了一个高性能的解决方案。本系列文章将讲解IWA的基本概念，并详细介绍如何在南大通用GBase 8s中安装和配置IWA。

IWA概述

什么是IWA?

IWA（In-Memory Warehouse Accelerator，内存数据仓库加速器）是一种基于内存的数据仓库技术，它通过将数据加载到内存中来提高查询性能。与传统的磁盘存储相比，内存存储可以显著减少数据访问延迟，实现更快的数据处理速度。

本文将介绍GBase 8s 中IWA的安装部署，并给出使用IWA的详细示例。

IWA优势

快速响应： 利用内存的高速访问能力，IWA能够实现对复杂查询的快速响应。

并行处理： IWA支持多线程并行处理，进一步提高数据处理效率。

易于集成： IWA与GBase 8s数据库紧密集成，无需复杂的配置即可使用。

使用版本

本文使用的数据库版本和IWA的版本如下：

GBase8sV8.8_AEE_3.5.0_2O2_AP20230726_1_833699_RHEL6_x86_64.tar

IWA_AEE_3.5.0_2O2_AP20230726_1_833699_RHEL6_x86_64.tar
