Paper accepted at EuroSys’25
Our paper "CAPSys: Contention-aware task placement for data stream processing" was accepted at EuroSys'25! We performed an empirical evaluation study to show that task placement not only significantly affects streaming query performance but also the convergence and accuracy of auto-scaling controllers. To address this issue, we propose CAPSys, an adaptive resource... More
