node.js get data from redis cluster, with ioredis, zrange method not returns correct number of data

Question

I use this: redisClient.zrange(key, 1, 1) and try to get all data by that key, but sometimes some data from list is missing, but when i check in redis data is there, also by c# client everything is ok. Any ideas?

Answer 1

For zrange command, the index is zero-based. 0 is the index for the first element, and -1 is the index for the last element.

To get all data for the given key:

zrange key 0 -1
