WebAug 19, 2024 · DynamoDB currently retains up to 5 minutes (300 seconds) of unused read and write capacity. During an occasional burst of read or write activity, these extra capacity units can be consumed quickly—even faster than the per-second provisioned throughput capacity that you've defined for your table. WebDynamoDB charges you for the reads that your application performs on your tables in terms of read request units. 1 read request unit (RRU) = 1 strongly consistent read of up to 4 KB/s = 2 eventually consistent reads of up to 4 KB/s per read. 2 RRUs = 1 transactional read request (one read per second) for items up to 4 KB.
