Defining the execution semantics of stream processing engines

Lorenzo Affetti, Riccardo Tommasini, Alessandro Margara, Gianpaolo Cugola, Emanuele Della Valle

Harnessing sliding-window execution semantics for parallel stream processing

Gabriele Mencagli, Massimo Torquati, Fabio Lucattini, Salvatore Cuomo, Marco Aldinucci
2018 Journal of Parallel and Distributed Computing  
According to the recent trend in data acquisition and processing technology, big data are increasingly available in the form of unbounded streams of elementary data items to be processed in real-time.  ...  In this work we focus on the relationship between the various existing sliding window semantics and the way the query processing is performed from the parallelism perspective.  ...  The next section will provide a brief background on Data Stream Processing by presenting a categorization of the different sliding window semantics.  ...

Modeling the execution semantics of stream processing engines with SECRET

Nihal Dindar, Nesime Tatbul, Renée J. Miller, Laura M. Haas, Irina Botan
2012 The VLDB journal  
There are many academic and commercial stream processing engines (SPEs) today, each of them with its own execution semantics.  ...  Conclusion and future work The SECRET model describes important differences in the semantics underlying stream processing models. We developed SECRET by studying both academic and industrial SPEs.  ...  [15] generalizes the denotational semantics approach of STREAM CQL.

An Efficient Method for Stream Semantics over RDMA

Patrick MacArthur, Robert D. Russell
2014 2014 IEEE 28th International Parallel and Distributed Processing Symposium  
Unlike TCP, which is a stream-oriented protocol, RDMA is a messageoriented protocol, and the OFA verbs library for writing RDMA application programs is more complex than the TCP sockets interface.  ...  This paper presents a communication algorithm that has been implemented in the UNH EXS stream-oriented mode to allow dynamic switching between sending transfers directly to user memory and sending transfers  ...  However, due to the ubiquity of the byte stream-oriented TCP/IP protocol, most applications expect byte stream semantics.  ...
