trash 很费,实际中没用,trash 的副本在fe中元数据都是必定不存在的,即使手工把它从trash 中拉回来,在fe 元数据也不含它, 把它搞回来后, 都还不能用。 以前doris 很多代码bug, 包括副本迁移等是不是丢数据、 一个tablet的所有副本都可能被删干净,留着trash 可能是防一手的。 但现在这些bug 都已经解决了, 线上用户也没遇到过要从trash 来捞回来的情况。
真正的回收站是 fe catalog recycle bin, 这部分的数据在BE中是一直在data目录中的,跟trash没关系, 可以通过recover 命令把 fe recycle bin 中的数据给恢复过来。
线上给用户建议时,都是建议直接把这个值设置为0的。
后续再提个pr改下这个默认值吧
