Batch value insert in Redis list

Question

Is there a way to store multiple values in a Redis list at the same time? I can only find a way to insert 1 value at the time in a list.

I've been looking at the following commands documentation: http://redis.io/commands

update: I have created a ticket for this feature.

Answer 1

You can use a pipeline, if using redis-py you could check out the below, I ran this on an aws instance of redis elasticache and found the following:

import redis
rs = redis.StrictRedis(host='host', port=6379, db=0)
q='test_queue'

Ran in 0.17s for 10,000 vals

def multi_push(q,vals):
    pipe = rs.pipeline()
    for val in vals:
        pipe.lpush(q,val)
    pipe.execute()

Ran in 13.20s for 10,000 vals

def seq_push(q,vals):
    for val in vals:
        rs.lpush(q,val)

~ 78x faster.

Answer 2

Yeah, it doesn't look like that's possible. You might be able to use MULTI (transactions) to store multiple values in an atomic sequence.
