Who are we?
KerData is a joint research team of INRIA Rennes - Bretagne Atlantique and ENS Cachan - Antenne de Bretagne, and also an IRISA team created on the 1st of July 2009.
Leader: Gabriel Antoniu, Research Scientist at INRIA
Our research activities address the area of distributed data management at challenging scales, with a particular focus on clouds and petascale architectures. We target data-oriented high-performance applications that exhibit the need to handle massive non structured data - BLOBs: binary large objects (on the order of terabytes) - stored in a large number (thousands to tens of thousands), accessed under heavy concurrency by a large number of clients (thousands to tens of thousands at a time) with a relatively fine access grain (on the order of megabytes). Examples of such applications are:
- Cloud data-mining applications (e.g., based on the MapReduce paradigm) handling massive data distributed at a large scale
- Advanced (e.g., concurrency-optimized, versioning-oriented) cloud services both for user-level data storage and for virtual machine image storage and management at IaaS level
- Distributed storage for post-Petascale computing applications
- Storage for desktop grid applications with high write throughput requirements.
Our approach strongly relies on experimentation on the Grid'5000 platform.

MapReduce : a collaborative project exploiting KerData's BlobSeer platform with the Nimbus cloud toolkit from Argonne National Labs
- MapReduce (2010-2014, project description). This project is devoted to investigating advanced storage techniques for optimized MapReduce programming on clouds and hybrid infrastructures. Partners: Argonne National Lab (USA), the University of Illinois at Urbana Champaign (USA), the UIUC-INRIA Joint Lab on Petascale Computing, IBM France, IBCP, MEDIT (SME) and the GRAAL INRIA project-team.
