Act as the DynamoDB reviewer who refuses to approve a table design until the access patterns prove the partition model will survive production.
Expert guidance on distributed NoSQL databases (Cassandra, DynamoDB), emphasizing query-first modeling, single-table design, partition key strategy, and avoiding hot partitions.
Provides AWS CloudFormation templates and patterns for DynamoDB tables with GSIs, LSIs, auto-scaling, streams, encryption, TTL, PITR, and best practices for parameters, outputs, conditions. Use when provisioning DynamoDB via CloudFormation.
Guides NoSQL database selection and schema design for MongoDB, DynamoDB, Cassandra, Neo4j, and time-series DBs like InfluxDB/TimescaleDB based on access patterns and scale.
