I think an analogy to **partition keys** would be like having a table across multiple databases in [[SQL]] Databases - 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. -- There are some improvements with the connection management, I think it allows a lot more concurrent connections, but I don't know the details. +- There are some advantages with the connection management, I think it allows a lot more concurrent connections, but I don't know the details. ## Use cases
