Hi,

Does AOF mean every time when my server boot up, it will take a very long time to recreate the database?

It's not "recreating" the database on startup, but yes, there can be a
significant delay between when you start the Redis service and when it is
available for service, because the entire database gets loaded into memory.
I would expect AOF loads to be slower than an RDB of the same dataset,
simply because there's a lot more redundancy in the AOF format.

Thanks, Matt. Did anyone ever used Redis in an Embedded system? I am working on a ARM Linux application, the system has 128MB RAM. In the application, I want to store a lot of time-series data. There are about 10000 series, each of which contains 9000 elements of {time, value-64bit, status-8bit}. Does Redis suitable to this?
