Coded Data Rebalancing for Decentralized Distributed Databases
K V Sushena Sree, Prasad Krishnan
The performance of replication-based distributed databases is affected due to non-uniform storage across storage nodes (also called \textit{data skew}) and reduction in the replica…
Blind Updates in Coded Caching
Suman Ghosh, Prasad Krishnan, Lakshmi Prasad Natarajan
We consider the centralized coded caching system where a library of files is available at the server and their subfiles are cached at the clients as prescribed by a placement deliv…
An Umbrella Converse for Data Exchange: Applied to Caching, Computing, and Shuffling
Prasad Krishnan, Lakshmi Natarajan, V. Lalitha
The problem of data exchange between multiple nodes with storage and communication capabilities models several current multi-user communication problems like Coded Caching, Data Sh…
Low Complexity Distributed Computing via Binary Matrices with Extension to Stragglers
Shailja Agrawal, Prasad Krishnan
We consider the distributed computing framework of MapReduce, which consists of three phases, the Map phase, the Shuffle phase and the Reduce phase. For this framework, we propose…
Coded Data Rebalancing: Fundamental Limits and Constructions
Prasad Krishnan, V. Lalitha, Lakshmi Natarajan
Distributed databases often suffer unequal distribution of data among storage nodes, which is known as `data skew'. Data skew arises from a number of causes such as removal of exis…
Subexponential and Linear Subpacketization Coded Caching via Projective Geometry
Hari Hara Suthan Chittoor, Prasad Krishnan, K V Sushena Sree +1
Large gains in the rate of cache-aided broadcast communication are obtained using coded caching, but to obtain this most existing centralized coded caching schemes require that the…
