Complex pattern matching in complex structures: The XSeq approach
2013
2013 IEEE 29th International Conference on Data Engineering (ICDE)
Preserved Fulltext
There is much current interest in applications of complex event processing over data streams and of complex pattern matching over stored sequences. ...
XSeq achieves higher expressiveness through an extension of XPath based on Kleene-* pattern constructs, and achieves very efficient execution, on both stored and streaming data, using Visibly Pushdown ...
CONCLUSION The XSeq system supports a powerful language extension to XPath which is effective at expressing complex sequence patterns over both stored and streaming XML data. ...

This complex application serves the needs of doctors and researchers and provides real-time support for streams of patient data. ...
Such applications not only call for large-scale analytics, but also for real-time streaming support, smaller analytics at interactive speeds, data visualization, and cross-storage-system queries. ...
After that, we outline our support for exploratory analytics. We then note how BigDAWG handles streaming data and complex analytics. ...

This separation often leads to I/O redundancy (e.g., write data twice to disk or transfer data twice over the network) and interference (e.g., I/O bottlenecks when collecting data streams and writing archival ...
In this position paper, we argue for a unified ingestion and storage architecture for streaming data that addresses the aforementioned challenge. ...
Given the complexity of stream SQL semantics and the support they require for handling state for such operations, it is important to understand how a stream storage system can sustain and optimize such ...
