Flink-ER: An Elastic Resource-Scheduling Strategy for Processing Fluctuating Mobile Stream Data on Flink

Table 3

Conclusions of the experiment.

DSPS	Scheduling strategy	Advantage	Disadvantage	Applicable scenario
Flink	Default scheduling strategy	Exactly once processing	Performance bottleneck	Constant and invariable processing load
Sra-stream [12]	First-fit and latency-sensitive runtime-aware-based scheduling	Stateful data scheduling	Scheduling performance fluctuation	Little stateful data
Flink-ER	Flow-network-based dynamic scheduling	Accurate breaking of bottleneck with lower overhead	Instantaneous break out	Large-scale stateful data
