为了体验5.7.11版本带来的新体验,俺也是迫不及待的想测试一下,新的特性和新功能。这几天心里一直想着的就是5.7.11 修复版的mysqlpump。在MySQL 5.7.11之前官方也明确说了mysqlpump 不支持一致性备份。
直到5.7.11中被修复了。其中最为有看点的就是:
1. 支持基于表的多线程导出功能(--default-parallelism,默认为2,--parallel-schemas,控制并行导出的库)
2. 导出的时候带有进度条(--watch-progress,默认开启)
3. 支持直接压缩导出导入(参数--compress-output,而且支持ZLIB和LZ4)
数据库:MySQL 5.7.11
系统:CentOS6.5 x64
测试数据量:6.1G
