Design and Deployment of a Sharded Cluster for the KASCADE Cosmic-ray Data Centre
KASCADE Cosmic-ray Data Centre (KCDC) makes publicly available the data from the astroparticle-physics experiment KASCADE. The system will eventually hold over 20 TB of data, or nearly half a billion events. Since 2015 it has been using the NoSQL database MongoDB as its storage back-end.
The goal of this project is to assist the KCDC database from a single server to a sharded (partitioned) cluster. In particular, you will be required to select and evaluate optimal shard keys for partitioned collections.
This is a joint project between the Steinbuch Centre for Computing (SCC) and the Institute for Nuclear Physics (IKP).
- analyse common work flows of KCDC from the point of view of database operations
- identify candidates for shard keys
- deploy a MongoDB cluster and activate sharding
- evaluate performance
A possibility exists to extend the project with additional goals to meet the requirements of a Master thesis.
- familiarity with MongoDB and sharding
- basic administrator-level knowledge of Linux
