Answer
Sharding early adds unnecessary complexity; sharding late causes heavy balancing, hotspots, and downtime. Ideal timing depends on write throughput and dataset size.
Quick Answer
Sharding too early: added complexity and operational overhead before you need it, harder to change shard key later. Sharding too late: migrating a huge existing collection to sharding is painful and time-consuming, poor shard key choice under pressure. Right time: when a single replica set reaches its limits (write throughput, storage, or working set exceeds available RAM). Start with a solid shard key design before you need sharding.
