In support of workload-aware streaming state management
2020
USENIX Workshop on Hot Topics in Storage and File Systems
Preserved Fulltext
This paper surfaces the limitations of established practices for streaming state management and advocates for configurable streaming backends, tailored to the state requirements of each operator. ...
We question the suitability of such general-purpose stores for streaming workloads and argue that they incur unnecessary overheads in exchange for state management capabilities. ...
A flexible testbed for state management To explore the potentials of a more flexible state management approach, we have implemented a testbed on top of the Timely Dataflow stream processor [19] . ...

Existing dataflow-based programming models for DL---both static and dynamic declaration---either cannot readily express these dynamic models, or are inefficient due to repeated dataflow graph construction ...
Experiments comparing Cavs to two state-of-the-art frameworks for dynamic NNs (TensorFlow Fold and DyNet) demonstrate the efficacy of this approach: Cavs achieves a near one order of magnitude speedup ...
We plot for one epoch, both the (averaged) absolute time for graph construction and it percentage of the overall time. ...
