As this threshold is based on prior domain knowledge and has an unpredictable relation to output size, its use faces challenges in large-data situations like online, distributed or out-of-core scenarios. We propose two alternative parameters, a targeted percentile size reduction and a total output size limit, to increase flexibility in those scenarios.Attribution 4.0 International LicenseHuman centered computingScientific visualizationMathematics of computingTopologySoftware and its engineeringUltralargescale systems10.2312/pgv.2020107775-79
