- Tables also have **sort keys**, this determines how records are ordered, and you can only query contiguous records, I think you cannot filter nor change the order (maybe only reverse the default order)
- So basically **partition keys** and **sort keys** determines how the table can be queried. This limitations is the tradeoff that makes [[DynamoDB]] fast.
