NDPPlugin安装

openGauss-5.1.0版本已经默认编译安装NDPPlugin插件,使用步骤如下:

1.获取LibSmartScan_5.1.0_openEuler_aarch64.tar.gz并解压。

tar -zxvf LibSmartScan_5.1.0_openEuler_aarch64.tar.gz

2.添加如下环境变量:

export LD_LIBRARY_PATH=/path/to/LibSmartScan_5.1.0_openEuler_aarch64/LibSmartScan_ThirdParty/ceph/openEuler_2003_armlib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/path/to/LibSmartScan_5.1.0_openEuler_aarch64/LibSmartScan_ThirdParty/rpc/openEuler_2003_armlib:$LD_LIBRARY_PATH

3.postgresql.conf添加guc参数:

shared_preload_libraries = 'ndpplugin'
synchronize_seqscans = off

4.启动libsmartscan服务,见 libsmartscan安装

5.创建数据库并连接数据库开始使用。

openGauss=# create extension ndpplugin;
CREATE EXTENSION
