Hash-Based Sharding

horizontal sharding

Distribute data using hash function on shard key

Algorithm
hash
Scalability
medium
Complexity
low

Advantages:

  • Even data distribution
  • Simple implementation
  • Good for random access
  • Predictable performance

Considerations:

  • Difficult to add/remove shards
  • Range queries are expensive
  • Hot keys can cause imbalance
  • No locality preservation

Best Use Cases:

High-throughput OLTP systems, user data, session storage
