In-Memory Big Data Management and Processing: A Survey

Hao Zhang, Gang Chen, Beng Chin Ooi, Kian-Lee Tan, Meihui Zhang
2015 IEEE Transactions on Knowledge and Data Engineering  
We are witnessing a revolution in the design of database systems that exploits main memory as its data storage layer.  ...  Growing main memory capacity has fueled the development of in-memory big data management and processing. By eliminating disk I/O bottleneck, it is now possible to support interactive data analytics.  ...  We would like to thank the anonymous reviewers, and also Bingsheng He, Eric Lo and Bogdan Marius Tudor, for their insightful comments and suggestions.  ...

As a hybrid of MPP database and Hadoop, it inherits the merits from both parties. It adopts a layered architecture and relies on the distributed file system for data replication and fault tolerance.  ...  In addition, it is standard SQL compliant, and unlike other SQL engines on Hadoop, it is fully transactional.  ...  Queries use logic length in the transaction snapshot when scanning a file.  ...

A1: A Distributed In-Memory Graph Database [article]

Chiranjeeb Buragohain, Knut Magne Risvik, Paul Brett, Miguel Castro, Wonhee Cho, Joshua Cowhig, Nikolas Gloy, Karthik Kalyanaraman, Richendra Khanna, John Pao, Matthew Renzelmann, Alex Shamis (+2 others)
2020 pre-print
A1 is an in-memory distributed database used by the Bing search engine to support complex queries over structured data.  ...  The combination of in-memory storage and RDMA access requires rethinking how data is allocated, organized and queried in a large distributed system.  ...  Graph databases are not new in the database world and in recent years, they have been experiencing great interest in industry: some notable efforts in the open source space include Neo4J [20] , Apache  ...

Extending a methodology for migration of the database layer to the cloud considering relational database schema migration to NoSQL [article]

Rilinda Lamllari, Universität Stuttgart, Universität Stuttgart
2013
The advances in Cloud computing and in modern Web applications have raised the need for highly available and scalable distributed databases to accommodate the big data being created and consumed.  ...  In this master thesis we investigate the possibilities and limitations of mapping relational database schemas to NoSQL schemas when migrating the database layer to the Cloud.  ...  Initially we found difficulties in launching the cluster in some availability zones, like Eu-Ireland and Asia Pacific, while it was successful using US-West Oregon zone.  ...
