sharding-strategy

What problem does it solve?

This Skill helps you design horizontal partitioning (sharding) so your data and write throughput scale across nodes while minimizing hotspots, expensive cross-shard operations, and painful resharding later.

Core Features & Use Cases

• Partitioning scheme selection: Understand range, hash, and directory/lookup sharding, and when to use each.
• Shard-key decisioning: Pick the shard key that determines routing, query locality, and balanced load.
• Resharding and consistent hashing: Use consistent hashing to reduce data movement when scaling the cluster.
• Operational trade-offs: Plan for cross-shard queries/joins and distributed transactions, including failure modes like hot shards and skew.
• Replication relationship: Clarify that sharding splits data while replication copies shards for availability.

Quick Start

Use the sharding-strategy skill to design a shard key and partitioning scheme for your multi-tenant database so most queries remain single-shard and resharding is manageable.
