The myth of NoSQL (vs. RDBMS) “joins dont scale”

By | AWS, Database Administration & Monitoring, NoSQL, Oracle, Postgres, SQL Server | No Comments

I’ll reference Alex DeBrie article “SQL, NoSQL, and Scale: How DynamoDB scales where relational databases don’t“, especially the paragraph about “Why relational databases don’t scale”.
