数据对比结果： 新实例：# Keyspace db0:keys=1221,expires=1194,avg_ttl=116766

旧实例： # Keyspace db0:keys=1244,expires=1217,avg_ttl=114422

1221-1194=27 1244-1217=27 数据一致

[suxb201]

我猜是你查看 info 的时间不一样，期间发生了过期。你可以找几个 key 看看过期时间。

1221-1194=27 1244-1217=27 数据一致 这里的 keys 总数为什么不是强一致的

我猜是你查看 info 的时间不一样，期间发生了过期。你可以找几个 key 看看过期时间。

这里写的脚本同时去查的源端和目标端，按理说应该是一致的，我这里可以在测试一下，目前源端是没有写入的，key 的数量是不变的

[stereon]

另外有拿了一套redis 实例，发现key 还是不一样 源端：# Keyspace db0:keys=28149,expires=28149,avg_ttl=221134947 目标端：# Keyspace db0:keys=25361,expires=25361,avg_ttl=223395805

@stereon 感觉和过期有关系，你可以找到具体有差异的 key，然后看一下过期时间吗？
