Benchmarking Hashing Algorithms for Load Balancing in a Distributed Database Environment
Alexander Slesarev, Mikhail Mikhailov, George Chernishev
Modern high load applications store data using multiple database instances. Such an architecture requires data consistency, and it is important to ensure even distribution of data…
Russian Web Tables: A Public Corpus of Web Tables for Russian Language Based on Wikipedia
Platon Fedorov, Alexey Mironov, George Chernishev
Corpora that contain tabular data such as WebTables are a vital resource for the academic community. Essentially, they are the backbone of any modern research in information manage…
Revisiting Data Compression in Column-Stores
Alexander Slesarev, Evgeniy Klyuchikov, Kirill Smirnov +1
Data compression is widely used in contemporary column-oriented DBMSes to lower space usage and to speed up query processing. Pioneering systems have introduced compression to tack…
S3M: Siamese Stack (Trace) Similarity Measure
Aleksandr Khvorov, Roman Vasiliev, George Chernishev +3
Automatic crash reporting systems have become a de-facto standard in software development. These systems monitor target software, and if a crash occurs they send details to a backe…
TraceSim: A Method for Calculating Stack Trace Similarity
Roman Vasiliev, Dmitrij Koznov, George Chernishev +3
Many contemporary software products have subsystems for automatic crash reporting. However, it is well-known that the same bug can produce slightly different reports. To manage thi…
Extending Databases to Support Data Manipulation with Functional Dependencies: a Vision Paper
Nikita Bobrov, Kirill Smirnov, George Chernishev
In the current paper, we propose to fuse together stored data (tables) and their functional dependencies (FDs) inside a DBMS. We aim to make FDs first-class citizens: objects which…
