BBoxDB streams: scalable processing of multi-dimensional data streams

Abstract BBoxDB Streams is a distributed stream processing system, which allows the handling of multi-dimensional data. Multi-dimensional streams consist n -dimensional elements, such as position data (e.g., two-dimensional positions cars or three-dimensional aircraft). The software an enhancement BBoxDB, key-bounding-box-value store that big supports continuous range queries and spatial joins; point non-point are supported. Operations in performed primarily on bounding boxes With user-defined filters (UDFs), custom formats can be decoded, box-based operations refined UDF decodes performs intersection tests real geometries WKT encoded elements). A unique feature ability to perform joins between elements previously stored For example, dynamic car efficiently joined with static street network.
