Re: Maximum number of queues(lists) redis instance can have

[Dvir Volk]

there shouldn't be a problem holding this sort of number of list or any other type

redis has a main dictionary holding objects in it, and each one is managed separately.

lists don't have a very high memory overhead, so no reason this should not work, at least in a 64 bit redis instance.

the most number of lists I've personally used is around 10M.

Hi, 

What would be the maximum number of queues a redis instance can have per instance ? In FAQ(What is the maximum number of keys a single Redis instance can hold?), its mentioned - "Redis can handle up to 2^32 keys, and was tested in practice to handle at least 250 million of keys per instance."

So can we assume redis supports at least 250 million of queues per instance ? Any idea what kind of data/value was used for the test ? 

Thanks & Regards

+1, never received reports of issues that were related to number of keys AFAIK.
Make sure you have enough RAM (and up to 2x the requirement if you
have a write-heavy workload) and everything should work ok.
