Serializable Snapshot Isolation in PostgreSQL [PDF]
Proceedings of the VLDB Endowment (PVLDB), Vol. 5, No. 12, pp.
1850-1861 (2012), 2012 This paper describes our experience implementing PostgreSQL's new serializable isolation level. It is based on the recently-developed Serializable Snapshot Isolation (SSI) technique. This is the first implementation of SSI in a production database release as well as the first in a database that did not previously have a lock-based serializable ...

Database support of detector operation and data analysis in the DEAP-3600 Dark Matter experiment [PDF]
, 2019 The DEAP-3600 detector searches for dark matter interactions on a 3.3 tonne liquid argon target. Over nearly a decade, from start of detector construction through the end of the data analysis phase, well over 200 scientists will have contributed to the project. The DEAP-3600 detector will amass in excess of 900 TB of data representing more than 10$^{10}

Analyzing Performance Characteristics of PostgreSQL and MariaDB on NVMeVirt [PDF]
arXivThe NVMeVirt paper analyzes the implication of storage performance on database engine performance to promote the tunable performance of NVMeVirt. They perform analysis on two very popular database engines, MariaDB and PostgreSQL. The result shows that MariaDB is more efficient when the storage is slow, but PostgreSQL outperforms MariaDB as I/O ...

Design, implementation and experiment of a YeSQL Web Crawler [PDF]
arXiv, 2012 We describe a novel, "focusable", scalable, distributed web crawler based on GNU/Linux and PostgreSQL that we designed to be easily extendible and which we have released under a GNU public licence. We also report a first use case related to an analysis of Twitter's streams about the french 2012 presidential elections and the URL's it contains.
