Primary Keys and Indexes:
DynamoDB uses primary keys and secondary indexes to organize and access data efficiently. The primary key consists of two parts: the partition key (also known as the hash key) and an optional sort key (also known as the range key). The partition key is used to distribute data across multiple storage partitions, while the sort key enables sorting and querying within each partition.
Partition Key (Hash Key): The partition key is used to determine the partition in which the item will be stored. DynamoDB distributes the data based on the partition key’s value. It is crucial to choose a partition key that distributes the data evenly to avoid hot partitions and achieve high scalability and performance.
Sort Key (Range Key): The sort key is optional and allows for hierarchical organization of data within a partition. It enables efficient querying of data based on range operations such as greater than, less than, or between. The combination of the partition key and sort key creates a composite key, which uniquely identifies each item in the table.
DynamoDB Partitioning Diagram:
Below is a simplified diagram illustrating how DynamoDB partitions data:
DynamoDB Table +-----------------------------------+ | Partition 1 | +-----------------------------------+ | Partition Key: A Sort Key: 1 | | Partition Key: B Sort Key: 2 | | Partition Key: C Sort Key: 3 | +-----------------------------------+ | Partition 2 | +-----------------------------------+ | Partition Key: D Sort Key: 1 | | Partition Key: E Sort Key: 2 | | Partition Key: F Sort Key: 3 | +-----------------------------------+ | Partition 3 | +-----------------------------------+ | Partition Key: G Sort Key: 1 | | Partition Key: H Sort Key: 2 | | Partition Key: I Sort Key: 3 | +-----------------------------------+
In DynamoDB, data is divided into partitions based on the partition key. Each partition can contain multiple items. Items within the same partition have fast access times and can be distributed across multiple storage nodes for scalability. By evenly distributing data across partitions, DynamoDB achieves high performance and can handle large workloads seamlessly.
Together, the partition key and sort key create a composite key that uniquely identifies each item in the table.
Global and Local Secondary Indexes:
DynamoDB supports both global secondary indexes (GSIs) and local secondary indexes (LSIs) to provide flexible querying options.
Global Secondary Index (GSI): A GSI is an index with a partition key and an optional sort key that can differ from the primary key. It enables efficient querying of data across different partitions, providing an alternative access pattern to the table. A GSI can be created during the table creation or added to an existing table.
Local Secondary Index (LSI): An LSI shares the same partition key as the table’s primary key but has a different sort key. It allows efficient querying of data within a single partition, providing additional query flexibility. An LSI must be defined at the time of table creation and cannot be added to an existing table later.
For more information, you can refer to the official DynamoDB documentation provided by AWS.
