If the workload is heavily unbalanced, meaning disproportionately focused on one or a few partitions, the operations will not achieve the overall provisioned throughput level. To get the most out of Amazon DynamoDB throughput, build tables where the hash key element has a large number of ...
I don't think the AWS CLI is uploading parts in parallel when configured for a request concurrency of 1 (see max_concurrent_requests = 1 which I posted above), which is how I configured it. I have also increased the AWS CLI part size to 50MB and see similar behavior, although it tak...
Amazon Aurora is a relational database service for OLTP workloads offered as part of Amazon Web Services (AWS). In this paper, we describe the architecture of Aurora and the design considerations leading to that architecture. We believe the central constraint in high throughput data processing has...
Bifrost makes extensive use of metadata stored in sequence headers. These metadata give semantic meaning to the contents of a ring, and enable blocks to communicate seamlessly with little or no user intervention. While sequence headers may be defined any way the user wishes, so long as they are...
trying to achieve a “perfect” distribution of partitions. In the case of this test, there is just a single partition for each node, so this is rather simple. We set the replication factor to one (1) in the case of this test, meaning each of the messages only resides...

For example, if a table has a very small number of heavily accessed hash key elements, possibly even a single very heavily used hash key element, traffic is concentrated on a small number of partitions – potentially only one partition. If the workload is heavily unbalanced, meaning disproporti...
