To work with DynamoDB more efficiently, we should follow some best practices while designing tables and items:
- Table best practices: DynamoDB tables are distributed across multiple partitions. For the best results, design your tables and applications so that read and write activities are spread evenly across all the items on your table, and avoid I/O hotspots that can degrade the performance of your application:
- Design for uniform data access across items in your table
- Distribute the write activity during data upload operations
- Understand the access platform for the time series data
- Item best practices: DynamoDB items are limited in size. However, there is no limit to the number of items in the table. Instead of storing large attribute data values in an item, consider the following alternative for your design:
- Use one-to-many tables instead of a large set of attributes
- Use multiple tables to support a varied access pattern
- Compress large attribute values
- Store large attribute values...
