Sharding distributes records across machines. It helps when a single database cannot meet storage or throughput needs and the workload can be partitioned effectively.
What makes a useful shard key?
Choose a key with many distinct values that spreads writes and supports common reads. A key that always increases may concentrate new writes on one range. Hashing can distribute those writes, while range partitioning can make bounded reads more efficient.
When does sharding add more cost than value?
Queries that omit the shard key may need to reach many shards. Cross-shard transactions, balancing and recovery add operational work. Test the real query mix and first rule out missing indexes, an undersized node or an inefficient data model.
