about dump.rdb in redis

[William Wu]

I have set maxmemory in redis.conf to 20G, but when I ran redis-cli,
inserting data with 15G, the memory consisting of virtual and physical
was always about 8G, why? Where was the remaining data? At the same
time, I checked the dump.rdb, whose size always ranged from 800M to
1.6G, and I searched in google which told me the lateset data replaced
old ones. If so, how should I do to avoid that situation?

Thanks!

Hi, how do you know that you inserted 15 GB of data *once* encoded
inside Redis data structures?

Cheers,
Salvatore

I counted my data, showing that was 15G. But I couldn't finish all the
data because my Java program threw the exception of heap space while I
set heap 8G.
