Glink - A Spatial Extension of Apache Flink

Glink is an extension of Apache Flink in the field of spatial data. It adds spatial processing operators and supports spatial data types that conform to the OGC standard. Glink can make spatial stream data processing as simple as writing a “WordCount” program.

Getting Started

Feature overview

Spatial Filter

Filter unbounded spatial data and optimize scenes with complex polygons as filter conditions.

Spatial Window KNN

Perform a KNN query on the spatial data in each window snapshot.

Spatial Join

Spatial join for unbounded spatial data, support stream and table join and double stream join.

Spatial Window DBSCAN

Perform DBSCAN clustering on the spatial data in each window snapshot, and output the clustering results in real time.
