---------------------------------
Summary: Optimize query side broadcast KNN join
Key: SEDONA-690
URL: https://issues.apache.org/jira/browse/SEDONA-690
Project: Apache Sedona
Issue Type: Bug
Reporter: Feng Zhang
We need to optimize the KNN join execution when the query side dataset is small
and broadcasted. This will enable much faster joins for use cases when joins a
smaller query dataset to a much big datasets. For example, when a few local
geometries find their k neighbors from global geospatial datasets (e.g., global
POIs). This seems to be a pretty common use cases for a batch-like KNN search.
