Wrong shard key—hotspots remain—teams then argue across ownership lines.
Horizontal scale
Sharding Strategy
Early sharding pre-spends application complexity. Clarify the boundary before choosing the build path.
Shard keys, routing and expansion paths—when truly needed.
Measure then change
Slow logs and load tests before index/schema changes.
Rollback-minded changes
Schema changes ship with scripts and rollback thinking.
Capacity planning
Estimate growth before sharding—avoid early complexity.
Sharding traps
These usually show up before a project starts—or right after a rushed launch.
Many cross-shard joins—it often surfaces only after production impact.
Expansions need long downtime—iteration and local integration slow down.
Ops tooling lacking—users feel it as inconsistent data or UX.
Assess-pilot-expand
Capacity math; shard key matches queries; middleware vs custom routing; expansion drills. Prove single-node tuning isn't enough, then shard. Lock shard key, cross-shard limits and ops cost—pilot small.
