In this paper, we design and implement a continuous event detection method for large mobile object data streams in a distributed parallel environment. The proposed method includes a distributed in-memory grid index and a continuous query processing method based thereon for effective event detection for moving objects. The proposed method detects pre-defined events by setting a region of interest and analyzing the location data stream of moving objects in a continuous manner. Subsequently, in addition to the table storing the location data of the moving object, we propose a method of separately maintaining a table storing the moving object data in the region of interest for continuously detecting events. The proposed method is implemented based on Apache Kafka, Spark, and Hbase, and performance is evaluated through various experiments.
