A universal compression strategy using sorting transformation

2019 · International Journal of Computational Science and Engineering

Although traditional universal compression algorithms can effectively utilise repetition located in a slide window, they cannot take their own advantages for some message source in which similar messages are distributed uniformly. In this paper, we …

Dynamic Tuple Scheduling with Prediction for Data Stream Processing Systems

2019

For data stream processing systems such as Apache Heron, workload imbalance across processing instances often causes significant system performance degradation. To mitigate such issues, Apache Heron leverages a naive throttling-based back-pressure scheme, which may lead …
