Nosql Expert

This is a solid mental model guide for Cassandra and DynamoDB that actually explains the core shift from relational thinking: model your queries first, not your entities. It covers the essentials like partition key cardinality, single-table design patterns, and why denormalization is your friend when storage is cheap and joins don't exist. The comparison tables and anti-pattern callouts (especially the ALLOW FILTERING warning) are genuinely useful if you're migrating from Postgres or debugging hot partitions in production. It won't teach you the APIs, but it will save you from designing a schema that looks like SQL with extra steps.
