When should I choose hashed over ranged sharding?

This skill recommends hashed sharding for write-heavy workloads with no range query requirements to eliminate hotspots and ensure random placement.

How does this skill help with shard key selection?

It provides a rigorous evaluation framework based on cardinality, frequency, and monotonicity to ensure even data distribution across all shards.

Can this skill assist with data residency requirements?

Yes, it includes specific patterns for zone sharding to map data to specific geographic regions or hardware tiers for compliance and performance.

Does it provide practical code examples?

Yes, it contains MongoDB shell (JavaScript) examples for checking cardinality, analyzing frequency, and implementing pre-split chunks.
