Hello. thank you very much for this. Very cool.

As the title says，in this case , it will lose some keys，will you consider covering this case?

Hi,

Thanks for the comment!

Yes, this is expected and unfortunately there's no way to fix it.

The only way to make a Redis dump from a specific point in time without affecting performance is by using BGSAVE, disabled on ElastiCache.

Rump tries to do its best with the commands that are actually enabled on ElastiCache, without affecting the performance of the source database. :)
