Figure 4: Fetching information from a single-table database This is the canonical example for using single-table design. We can handle access patterns that involve heterogeneous items while still getting the consistent performance we expect from DynamoDB. Use single-table design to reduce costs acro...
This blog post shows how to implement an ERD design by using a single-table design approach instead of using multiple tables. We use the higher-level programming interface for DynamoDB called DynamoDBMapper to demonstrate an example implementation based on Spring Boot. ...
Evaluate your table class selection Identify your unused resources Evaluate your table usage patterns Evaluate your streams usage Evaluate your provisioned capacity for right-sized provisioning Partition key design Sort key design Secondary indexes Large items Time series data Many-to-many relationships ...
In it, you’ll learn about foundational DynamoDB concepts and some of my favourite topics like streams and single table design. Highly recommended for both newcomers to DynamoDB and experienced users looking for a refresher." About the Author ...
What is single-table design Why single-table design is needed The downsides of single-table design The two times where the downsides of single-table design outweigh the benefits I recently did a live debate on this subject on Twitch with Rick Houlihan and Edin Zulich. Check out the recording...
Design pattern for time series dataTime series table examples General design principles in Amazon DynamoDB recommend that you keep the number of tables you use to a minimum. For most applications, a single table is all you need. However, for time series data, you can often best handle it ...
Note that I discussed an enhanced version of this during my2022 talk at AWS re:Invent. I talked about 'vertical sharding', which can be a nice use of single-table design principles to split a single entity into multiple records to save on costs. For this example, imagine our underlying ...
DynamoDB Single Table Design Support Ability to transform data before saving or retrieving items Strict data modeling (validation, required attributes, and more) Support for DynamoDB Transactions Powerful Conditional/Filtering Support Callback & Promise support ...
It supports Single Table Design, where different model types are stored in a single DynamoDB table. Each document has a unique ID which is used as the table hash key, ensuring documents are always evenly spread across all partitions. Not all DynamoDB functions are available, but DynamoDM is...
Learn about the technology you’re adopting so you can design for it and configure it appropriately. Managed services are wonderful, but you still need to understand the tool and how to utilize it to meet your needs. Clearly understand the “why” of your migration project; for example, if...
