The primary key that uniquely identifies each item in an Amazon DynamoDB table can be simple (a partition key only) or composite (a partition key combined with a sort key). You should design your application for uniform activity across all partition keys in the table and its secondary index...

An item collection in DynamoDB, which consists of items sharing the same partition key, can span multiple partitions throughadaptive capacity. This can occur when an item collection experiences high read/write throughput or exceeds the per partition storage quota. When an item collection...
You can partition data separately based on the partition key to allow different access patterns. The base table’s primary key attributes are always part of the global secondary index, and you can choose which other attributes from the table to project into an index. You can avoid having to ...
Because they have the same partition key of Tom Hanks, they are in the same item collection. You can use DynamoDB's Query API operation to read multiple items with the same partition key. Thus, if you need to retrieve multiple heterogenous items in a single request, you organize those ...
Asimple keyconsists of a partition key (hash attribute) that determines the partition (physical storage internal to DynamoDB) in which the item will be stored. In this case, the partition key should be unique for each item. Acomposite keyconsists of a partition key (hash attribute) and a ...
For those familiar with SQL looking to learn CQL, you may want to look at this blog on best practices. Within CQL tables data is organized into partitions, with primary keys comprised of a partition key and clustering key.You can learn more about denormalization, partitioning and other aspects...
Queries require equality filters on every partition key, otherwise when a query is executed an exception will result. Consider a model with 2 partition keys id1 and id2:class IteratorExample extends db.Model { static KEY = { id1: S.str, id2: S.int } static SORT_KEY = { sk1: S....
