![]() Redis is, after all, a direct result of its current design. So for now there are no plans to create an on disk backend for Redis. In the past the Redis developers experimented with Virtual Memory and other systems in order to allow larger than RAM datasets, but after all we are very happy if we can do one thing well: data served from memory, disk used for storage. Why does Redis keep its entire dataset in memory? Have a lot of memory in 64-bit systems, so in order to run large Redis servers a 64-bit system is more or less required. But of course the advantage is that you can This is because pointers take 8 bytes in 64-bit systems. ![]() Use the redis-benchmark utility to generate random data sets then check the space used with the INFO memory command.Ħ4-bit systems will use considerably more memory than 32-bit systems to store the same keys, especially if the keys and values are small.
