pg_profile类似于Oracle的AWR(Automatic Workload Repository)架构,能够在指定时间间隔内生成快照,并通过HTML格式的报告来解释这些快照之间的统计数据差异。 1.2、扩展架构 扩展由四部分组成: 历史存储库是采样数据的存储库。存储库是一组扩展表。 样本管理引擎是一组功能,用于采集样本并通过从中删除过时的样本数据来支持...
1. 支持多种数据源:pgloader 支持从MySQL、SQLite、CSV 文件、固定宽度文本文件等多种数据源迁移数据到PostgreSQL,同时也支持从 MicrosoftSQL Server和 Oracle数据库迁移数据。 2. 高效数据导入:pgloader 使用了 PostgreSQL 的 `COPY` 协议进行数据流式传输,这使得数据迁移的速度比常规 SQL 插入快得多。
