TLDR
Cassandra is a distributed storage system for managing very large amounts of structured data spread out across many commodity servers, while providing highly available service with no single point of failure.Abstract:
Cassandra is a distributed storage system for managing very large amounts of structured data spread out across many commodity servers, while providing highly available service with no single point of failure. Cassandra aims to run on top of an infrastructure of hundreds of nodes (possibly spread across different data centers). At this scale, small and large components fail continuously. The way Cassandra manages the persistent state in the face of these failures drives the reliability and scalability of the software systems relying on this service. While in many ways Cassandra resembles a database and shares many design and implementation strategies therewith, Cassandra does not support a full relational data model; instead, it provides clients with a simple data model that supports dynamic control over data layout and format. Cassandra system was designed to run on cheap commodity hardware and handle high write throughput while not sacrificing read efficiency.read more

Yugala: Blockchain Based Encrypted Cloud Storage for IoT Data
TL;DR: This paper proposes a novel lightweight decentralized encrypted cloud storage architecture called, Yugula, which maintains file confidentiality, removes the centralized data deduplication and increases file integrity by using blockchain, and discusses two approaches for file confidentiality with data dedUplication: one uses double hashing and the other symmetric encryption.

IBIS: interposed big-data I/O scheduler
Yiqi Xu,Adrian Suarez,Ming Zhao +2 more
TL;DR: Experiments show that the IBIS provides strong performance isolation for one application against another highly I/O-intensive application, and enforces good proportional sharing of the global bandwidth among competing parallel applications.
