golang 实现的零依赖、高性能、并发 mysqldump 工具
golang 实现的零依赖、高性能、并发 mysqldump 工具。
项目地址: https://github.com/dengjiawen8955/mysqldump/blob/master/README-zh.md
文章地址: https://bmft.tech/#/2-program/0325-golang-implements-mysqldump
自定义 Writer: 如本地文件、多文件储存、远程服务器、云存储等。（默认控制台输出）。 支持所有 MYSQL 数据类型. 支持 INSERT Merge, 大幅提升数据恢复性能
