EasyFlinkCEP: big event data analytics for everyoneEasyFlinkCEP: big event data analytics for everyone Σύντομη Δημοσίευση σε Συνέδριο Conference Short Paper 2023-06-132021enThis work has received funding from the EU Horizon 2020 research and innovation program INFORE under grant agreement No 825070.FlinkCEP is the Complex Event Processing (CEP) API of the Flink Big Data platform. The high expressive power of the language of FlinkCEP comes at the cost of cumbersome parameterization of the queried patterns, acting as a barrier for FlinkCEP's adoption. Moreover, properly configuring a FlinkCEP program to run over a computer cluster requires advanced skills on modern hardware administration which non-expert programmers do not possess. In this work (i) we build a novel, logical CEP operator that receives CEP pattern queries in the form of extended regular expressions and seamlessly re-writes them to FlinkCEP programs, (ii) we build a CEP Optimizer that automatically decides good job configurations for these FlinkCEP programs. We also present an experimental evaluation which demonstrates the significant benefits of our approach.http://creativecommons.org/licenses/by/4.0/3029–303330th ACM International Conference on Information & Knowledge ManagementProceedings of the 30th ACM International Conference on Information & Knowledge ManagementGiatrakos_et_al_CIKM_2021.pdfChania [Greece]Library of TUC2023-06-13application/pdf1.7 MBfree Giatrakos Nikolaos Γιατρακος Νικολαος Kougioumtzi Eleni Kontaxakis Antonios Κονταξακης Αντωνιος Deligiannakis Antonios Δεληγιαννακης Αντωνιος Kotidis, Yannis Association for Computing Machinery (ACM) Big Data FlinkCEP Complex Event Processing Optimizer
