    Introduction

    Sharding partitions a collection across multiple replica sets, letting you scale beyond a single machine's storage or throughput. Choose the shard key carefully — it can't be changed easily and dictates write distribution.

    Syntax reference

    js
    sh.shardCollection("shop.orders", { customerId: "hashed" });
