1. 11. Queryable Workflows: Extending Dataflow Streaming with Dynamic Request/Reply Communication

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Chengyang Huang; [2023]
   Nyckelord :Stream Processing; Observability; SQL Query Engine; Stateful Serverless; Searbetning av Strömmar; Observabilitet; SQL-förfrågningsmotor; Stateful Serverless;

   Sammanfattning : Stream processing systems have been widely adopted in applications such as recommendation systems, anomaly detection, and system monitoring due to their real-time capabilities. Improving observability in stream processing systems can further expand their application scenarios, including the implementation of stateful serverless applications. LÄS MER

3. 12. A Comparative Evaluation of Failover Mechanisms for Mission-critical Financial Applications in Public Clouds

   Master-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Albert Gustavsson; [2023]
   Nyckelord :Failover; Cloud computing; Cloud-native; Redundancy;

   Sammanfattning : Computer systems can fail for a vast range of reasons, and handling failures is crucial to any critical computer system. Many modern computer systems are migrating to public clouds, which provides more flexible resource consumption and in many cases reduced costs, while the migration can also require system changes due to limitations in the provided cloud environment.

4. 13. Parallel Kafka Producer Applications : Their performance and its limitations

   Master-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Arvid Sundbom; [2023]
   Nyckelord :Distriubted Systems; Parallel Systems; Apache Kafka; Rust; OpenMP;

   Sammanfattning : "This paper examines multi-threaded Kafka producer applications, and how the performance of such applications is affected by how the number of producer instances relates to the number of executing threads. Specifically, the performance of such applications when using a single producer instance, shared among all threads, and when each thread is allotted a separate, private instance, is compared.

5. 14. Secure log-management for an Apache Kafka-based data-streaming service

   Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Hjalmar Kull; Mirza Hujic; [2023]
   Nyckelord :Apache Kafka;

   Sammanfattning : This thesis aims to investigate the prospect of using Apache Kafka to manage data streams based on secrecy/classification level and separate these data streams in order to meet the requirement set by the secrecy/classification levels. Basalt AB has the responsibility of managing classified data for private and state actors, including the Swedish Armed Forces and other organizations. LÄS MER

7. 15. Auto-Tuning Apache Spark Parameters for Processing Large Datasets

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Shidi Zhou; [2023]
   Nyckelord :Apache Spark; Cloud Environment; Spark Configuration Parameter; Resource Utilization; Ridge Regression; Elastic Net; Random Forest; Deep Neural Network; Bayesian Optimization; Particle Swarm Optimization.; Apache Spark; Molnmiljö; Apache Spark konfigurationsparameter; Resursutnyttjande; Ridge-regression; Elastisk nät; Slumpskog; Djupt neuralt nätverk; Bayesiansk optimering; Partikelsvärmsoptimering.;

   Sammanfattning : Apache Spark is a popular open-source distributed processing framework that enables efficient processing of large amounts of data. Apache Spark has a large number of configuration parameters that are strongly related to performance. Selecting an optimal configuration for Apache Spark application deployed in a cloud environment is a complex task. LÄS MER
