WebIt is challenging to develop a distributed stream processing system that supports both snapshot and continuous queries over a large scale of spatio-textual data with low latency and ... support spatial join, range query and kNN query. Location-Spark [21] extends Spark with a query scheduler and local query executors. WebGeoMesa is an open source suite of tools that enables large-scale geospatial querying and analytics on distributed computing systems. GeoMesa provides spatio-temporal indexing on top of the Accumulo, HBase, Google Bigtable and Cassandra databases for massive storage of point, line, and polygon data. GeoMesa also provides near real time stream ...

WebFeb 28, 2024 · Data stream processing systems are used to continuously run mission-critical applications for real-time monitoring and alerting. These systems require high throughput and low latency to process incoming data streams in real time. However, changes in the distribution of incoming data streams over time can cause partition skew, … WebJun 9, 2024 · Distributed Stream KNN Join. kNN join over data streams is an important operation for location-aware systems, which correlates events from different sources based on their occurrence locations. Combining the complexity of kNN join and the dynamicity of data streams, kNN join in streaming environments is a computationally intensive … WebJan 5, 2024 · We present a comprehensive overview of the kNN queries over high-dimensional data, which covers 20 kNN Search methods and 9 kNN Join methods. As per our knowledge, this is the first detailed study of the exact kNN approaches in high-dimensional data space. We systematically classify and compare existing strategies. robert graham homes midland tx
