Sounds like they need to use a lua function to ensure that pop and push operation remains atomic within the redis instance? For example: spopsadd local src_li

Sounds like they need to use a lua function to ensure that pop and push operation remains atomic within the redis instance? For example: spopsadd local src_list = ARGV[1] local dst_list = ARGV[2] local value = redis.call('spop', src_list) if value then -- avoid pushing nils redis.call('sadd', dst_list, value) end return value
