Recommended Sharding Strategies

Hash-based ShardingRecommended

Distribute data using hash function on primary key

Pros
  • Even distribution
  • Simple implementation
  • Good for read/write balance
Cons
  • Difficult to reshape
  • No range queries across shards

Range-based Sharding

Partition data by ranges of key values

Pros
  • Efficient range queries
  • Easy to add/remove shards
  • Intuitive
Cons
  • Hot spots possible
  • Uneven distribution
  • Needs rebalancing

Geographic Sharding

Partition by geographic region or data center

Pros
  • Low latency
  • Regulatory compliance
  • Fault isolation
Cons
  • Complex routing
  • Uneven load
  • Cross-shard queries
