The purpose of this paper is to investigate the possibility to instantiate a big data mart under one of the most popular and least complicated types of NoSQL databases; namely key-value store, the main challenge
Key-value stores: a practical overviewKey-Value stores: a practical overview Marc Seeger Computer Science and Media Ultra-Large-Sites SS09 Stuttgart, Germany September 21, 2009 Key-Value stores provide a high performance alternative to rela- tional database systems when it comes to storing and ...
There are a few advantages that a key-value store provides over traditional row-column-based databases. Thanks to the simple data format that gives it its name, a key-value store can be very fast for read and write operations. And key-value stores are very flexible, a valued asset in mo...
2006年Google在OSDI上发表的BigTable [1],被公认为Key-Value Store的开山之作,提供了大规模、高性能、高可用性的分布式数据存储解决方案。实际上Key-value数据库的概念至少可以追溯到1979年Ken Thompson发布的DBM库。除BigTable外,如Amazon的Dynamo [2]、Apache Cassandra、LinkedIn的Voldemort 和Berkeley DB [3]等键...
Log-structured merge tree (i.e., LSM-tree)-based key–value stores (i.e., KV stores) are widely used in big-data applications and provide high performance. NAND Flash-based Solid-state disks (i.e., SSDs) have become a popular storage device alternative to hard disk drives (i.e., ...

Major contributors to Key-Value Store development include Amazon's DynamoDB, Google's Bigtable, and Facebook's Cassandra. Functionality and Features Key-value stores function by storing data as a collection of key-value pairs in which the key operates as the unique identifier. Features of key-...
Region:Region is the basic unit of Key-Value data movement. Each Region is replicated to multiple Nodes. These multiple replicas form a Raft group. Node:A physical node in the cluster. Within each node, there are one or more Stores. Within each Store, there are many Regions. ...
For most key-value stores, the secret to its speed lies in its simplicity. The path to retrieve data is a direct request to the object in memory or on disk. The relationship between data does not have to be calculated by a query language; there is no optimization performed. They can ex...
Key-value stores have been out there for at least a good 30 years[1]. One of the most memorable projects is DBM, the initial database manager coded by Kenneth Thompson for Unix version 7 and released in 1979[2]. Engineers have faced issues related to these database systems, and have ...
