redis cluster batch actions

this is a small wrap base on node-redis

usage

const cluster = await RedisClusterBatch.init({
  host: "redis-cluster",
  port: 6379,
  slotsRefreshInterval: 5000,
});


// use batch action
await cluster.mSetPx(
  {
    key1: "value1",
  },
  7000
);
const result = await cluster.mGet(["key1"]);

// use node-redis client
await cluster.client.set("key1", "value1");
await cluster.client.get("key1");

redis cluster mget/mset

auto manage cluster slots

4 nodes cluster with mget 4000 keys will send with 4 mget query to each cluster node
