  1. 1. Code Generation for Accelerating Data Flow : Enhancing Pentaho Data Integration Performance

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Svensson; [2023]
    Keywords : ;

    Abstract : Pentaho Data Integration, called Kettle, is an ETL tool that functions as a no-code program. The tool, implemented in Java, enables users to create data flow structures via a graphical user interface and store them as XML files, which can be edited or executed. READ MORE

  3. 2. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands

    University essay from KTH/Tillämpad fysikalisk kemi

    Abstract : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. READ MORE

  4. 3. Replacing batch-based data extraction withevent streaming with Apache Kafka : A comparative study

    University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Author : Richard Axelsson; [2022]
    Keywords : etl; kafka connect; resource consumption; sql server;

    Abstract : For growing organisations that have built their data flow around a monolithic database server, anever-increasing number of applications and an ever-increasing demand for data freshness willeventually push the existing system to its limits, prompting either hardware upgrades or anupdated data architecture. Switching from an approach of full extractions of data at regularintervals to an approach where only changes are extracted, resource consumption couldpotentially be decreased, while simultaneously increasing data freshness.
