2. 1. Explainable and Resource-Efficient Stream Processing Through Provenance and Scheduling

   Author : Dimitrios Palyvos-Giannas; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Scheduling; Provenance; Stream Processing;

   Abstract : In our era of big data, information is captured at unprecedented volumes and velocities, with technologies such as Cyber-Physical Systems making quick decisions based on the processing of streaming, unbounded datasets. In such scenarios, it can be beneficial to process the data in an online manner, using the stream processing paradigm implemented by Stream Processing Engines (SPEs). READ MORE

4. 2. Scalable and Reliable Data Stream Processing

   Author : Paris Carbone; Seif Haridi; Peter Pietzuch; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; stream processing; data management; databases; distributed computing; data processing; fault tolerance; database optimisation; programming systems; data science; data analytics; computer science; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Data-stream management systems have for long been considered as a promising architecture for fast data management. The stream processing paradigm poses an attractive means of declaring persistent application logic coupled with state over evolving data. READ MORE

5. 3. Language-based Approaches to Safe and Efficient Distributed Programming

   Author : Xin Zhao; Philipp Haller; Roberto Guanciale; Wolfgang De Meuter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Programming languages; Distributed systems; Type system; Replicated data types; Computer Science; Datalogi;

   Abstract : Distributed systems address the increasing demand for fast access to resources and fault tolerance for data. Strong consistency ensures that all clients observe consistent data updates atomically on all servers in a distributed system, and it is widely used in systems such as relational databases.

6. 4. Optimization and Execution of Complex Scientific Queries

   Author : Ruslan Fomkin; Tore Risch; Marianne Winslett; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; scientific databases; query processing; data streams; cost-based query optimization; query rewritings; databases and Grids; Computer science; Datavetenskap; Data- och systemvetenskap; Computer Systems Sciences;

   Abstract : Large volumes of data produced and shared within scientific communities are analyzed by many researchers to investigate different scientific theories. Currently the analyses are implemented in traditional programming languages such as C++. READ MORE

7. 5. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

   Author : Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

   Abstract : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. READ MORE
