DynamoDB exposes a similar data model to and derives its name from Dynamo, but has a different underlying implementation. This public document was automatically mirrored from PDFy. From the very early replicated, database works, it is well known that when dealing with the, availability cannot be achieved simultaneously [2, 11]. SLAs defined based on the mean or median. To address, this issue, at Amazon, SLAs are expressed and measured at the, percentile of the distribution. Op de 9de november 1923, om 12 uur 30 in de namiddag, vielen voor de Feldherrnhalle, en op de binnenplaats van het voormalige ministerie van Oorlog te München, de volgende An important design consideration is to decide, the process of resolving update conflicts, i.e., whether conflicts, should be resolved during reads or writes.

State is stored as binary objects, (i.e., blobs) identified by unique keys. Algorithms, Management, Measurement, Performance, Design, Amazon runs a world-wide e-commerce platform that serves tens, of millions customers at peak times using tens of thousands of, servers located in many data centers around the world. Dynamo targets applications that operate with weaker consistency, (the “C” in ACID) if this results in high availability. Many traditional data, stores execute conflict resolution during writes and keep the read, complexity simple [7]. Voorraadbeheer, logistiek en planning zijn tot in perfectie geslepen.

This excess, functionality requires expensive hardware and highly skilled, In addition, the available replication technologies are limited and, typically choose consistency over availability. The paper is structured as follows. At this scale, small and large components fail, continuously and the way persistent state is managed in the face, of these failures drives the reliability and scalability of the, This paper presents the design and implementation of Dynamo, a, highly available key-value storage system that some of Amazon’s, achieve this level of availability, Dynamo sacrifices consistency, under certain failure scenarios. This paper presents the, design and implementation of Dynamo, another highly available. This requirement forces us to push the, complexity of conflict resolution to the reads in order to ensure, Figure 1: Service-oriented architecture of Amazon’s. Its operation environment is assumed to be non-hostile, and there are no security related requirements such as, authentication and authorization. consistently achieve their latency and throughput requirements. Dynamo is used to manage the state of services that have very, high reliability requirements and need tight control over the, tradeoffs between availability, consistency, cost-effectiveness and, applications with different storage requirements. of thousands of concurrently active sessions. amazon-dynamo-sosp2007.pdf (PDFy mirror) Item Preview remove-circle Share or Embed This Item.
