Evaluating the Cassandra NoSQL Database Approach for Genomic Data Persistency. [PDF]
Int J Genomics, 2015 Rapid advances in high‐throughput sequencing techniques have created interesting computational challenges in bioinformatics. One of them refers to management of massive amounts of data generated by automatic sequencers. We need to deal with the persistency of genomic data, particularly storing and analyzing these large‐scale processed data.

Workload‐Aware Performance Tuning for Multimodel Databases Based on Deep Reinforcement Learning
International Journal of Intelligent Systems, Volume 2023, Issue 1, 2023., 2023 Currently, multimodel databases are widely used in modern applications, but the default configuration often fails to achieve the best performance. How to efficiently manage and tune the performance of multimodel databases is still a problem. Therefore, in this study, we present a configuration parameter tuning tool MMDTune+ for ArangoDB.

Dependence‐Cognizant Locking Improvement for the Main Memory Database Systems
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 The traditional lock manager (LM) seriously limits the transaction throughput of the main memory database systems (MMDB). In this paper, we introduce dependence‐cognizant locking (DCLP), an efficient improvement to the traditional LM, which dramatically reduces the locking space while offering efficiency.
