What databases does the NoSQL Expert skill focus on?

This skill is specifically designed for distributed wide-column and key-value stores, with a primary focus on Apache Cassandra, Amazon DynamoDB, and ScyllaDB.

How does this skill help with database performance?

It provides patterns to avoid 'hot partitions,' strategies for even data distribution, and guidance on using partition keys effectively to ensure low-latency reads and writes at scale.

What is 'Single-Table Design' in this context?

Single-table design is a pattern primarily used in DynamoDB to store multiple entity types in one table, allowing the application to fetch related data in a single network request without joins.

Does it support relational database modeling?

While it explains the differences between SQL and NoSQL, its primary purpose is to help users move away from relational habits toward distributed NoSQL mental models like query-first design.

About

This skill equips Claude with specialized knowledge for designing and optimizing distributed wide-column and key-value stores. It focuses on the critical 'query-first' mental shift required for systems like Apache Cassandra and Amazon DynamoDB, moving away from relational entity modeling toward high-performance access patterns. Use this skill to implement single-table designs, optimize partition keys for horizontal scaling, and troubleshoot performance bottlenecks like hot partitions in high-traffic microservices.
