spop | A Spotify client running as a daemon , similar to mpd

SPOP [set] [count] was introduced in Redis v3.2 - https://redis.io/commands/spop , my REDIS version is 2.7.

How can I atomically pop several items from a SET using cli commands?

Is it possible to do something like...?

I'm trying to execute a basic transactional operation that contains two operations

1. Get the length of a set scard MySet
2. Pop the entire set with the given length : spop MySet len

I know it is possible to use smembers and del consecutively. But what I want to achieve is to get the output of the first operation and use it in the second operation and do it in a transaction. Here is what I tried so far:

I am looking on LPOP and LPOPRPUSH as a valid options for an atomic action to pop value. However I have a job that every 2 seconds pops 1000 values from that list - which is 1000 requests to Redis. I would have used SPOP which can return X values back in one request. But those are randon ones and not the most left ones. I do need to pop them from the left side of the list.

What are my options to do it the fastest, without locking and atomic? I have multiple servers that access this list and I can't retrieve duplicate values (That's why LRANGE doesn't work for me)

EDIT The more I'm thinking about it the more I see that I need to compromise and use SPOP.

The scenario is batching inserts into the DB with Redis. Instead of thousands inserts a sec to MySQL - I'm pushing to Redis and every 2sec get the values and insert in one go to MySQL.

I guess I can use SPOP if I will add timestamp to the actual value in Redis, and to avoid the possibility where a value can be stuck in the set forever I will run a loop of SPOP x 1000 until null.

I receive following output:

I am having trouble installing a package to my conda virtual environment through pip (not available through conda unfortunately) and I don't understand what is going wrong here, so I would greatly appreciate any help please! I'm trying to install the albopictus package through

pip install albopictus

but it fails with the following output:
