SPARC-Stream: A Sketch-Based Privacy-AwareResilient Compression Framework for High-Throughput Graph Stream Analytics

Modern data-intensive applications generate massive graph-structured data streams from social networks, financial systems, sensor infrastructures, and online services. Extracting meaningful insights such as heavy hitters, dense communities, and neighborhood relationships from these streams requires algorithms that are...

CODAQ: Context-Oriented Distributed Adaptive Query Processing for Large-Scale Graph and Data Systems

Modern data-driven applications increasingly rely on distributed graph databases and machine learning pipelines to extract knowledge from massive datasets. However, efficient query processing in distributed environments remains challeng-ing due to issues such as graph partitioning inefficiencies, dynamic connectivity u...

HYPERION-Q: A Graph-Guided Self-Validating and Hardware-Aware Framework for High-Performance Query Processing

Modern data management systems must simultaneously address three critical challenges: efficient query optimization for large queries, reliable detection of logical errors in database engines, and high-performance processing across heterogeneous hardware architectures. Traditional query optimizers rely on dynamic progra...
