Migrating to DynamoDB, Part 1: Lessons in Schema Design. The indexes property is an object that specifies the names and keys of the secondary indexes on your DynamoDB table. Relational database systems (RDBMS) and NoSQL databases have different strengths and weaknesses: These differences make database design different between the two systems: When using SDK or CLI, you need to use it as the table definition parameter when calling CreateTable operation.

The first query pattern is straight-forward -- that's a 1:1 relationship using a simple key structure. Table Indexes. “… for maximizing performance and minimizing throughput costs” 5. It follows the Adjacency List Design Pattern, which is a common way to represent relational data structures in DynamoDB. This is actually the case for all NoSQL databases, and DynamoDB is not an exception. They don't train the developers to think in DynamoDB. This post is the first in a two-part series about migrating to DynamoDB by Runscope Engineer Garrett Heel (see Part 2 ). Thanks for letting us know we're doing a good (dot). Discover the best practices for designing schemas, maximizing performance, and minimizing throughput costs when working with Amazon DynamoDB. DynamoDB, First Steps for Modeling Relational Data in DynamoDB, Example of Modeling Relational Data in DynamoDB, Best Practices for Querying and Scanning Data. sorry we let you down. The resulting DynamoDB JSON output can be then used to create DynamoDB table via DynamoDB CLI, SDK, CloudFormation, Serverless Framework etc. Flexible database monitoring. Selective Table Queries, Using Global Secondary Indexes to Create an Eventually It is worth mentioning that table names are UTF-8 encoded, case-sensitive, and should be between 3 and 255 characters long. DynamoDB schemas often have little room to grow given their lack of support for relational data (an almost essential function for evolving applications); the heavy-emphasis on single-table design to support relational-like access patterns, leaves customers with the responsibility of maintaining the correctness of denormalized data.
