java开发者使用PG jdbc驱动时,可以指定reWriteBatchedInserts连接参数来加速批量操作。如果reWriteBatchedInserts=true,JDBC驱动会重写批量insert转换成多行insert,从而限制数据库的调用次数。 例如: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 insert into foo (col1, col2, col3) values(1,2,3); insert...
SSL认证用于加密客户端和服务器之间的通讯数据,为敏感数据在Internet上的传输提供了一种安全保障手段。GaussDB(DWS)管理控制台提供了自签的证书供用户下载。使用该证书,用户需要配置客户端程序,使证书可用,此过程依赖于openssl工具以及java自带的keytool工具。
