DynamoDB
Also written as Amazon DynamoDB
AWS's fully managed NoSQL database, built for very fast, predictable performance at large scale, with a more restrictive query model than a relational database.
Think of it like
Like a massive, ultra-fast parcel locker system — retrieving a specific labeled locker is instant, but you can't easily browse or search across everything the way you could in a filing cabinet.
Junior or senior?
Junior sounds like
Has only used DynamoDB as a simple key-value store.
Senior sounds like
Designed their access patterns upfront and can describe hitting and working around that constraint.
Ask them
“What access pattern did you have to design around upfront when modeling data in DynamoDB?”
