Description
The first spatial aggregation in ESQL will demonstrate the use of extracting doc-values instead of source values for reading the field from lucene. This makes this aggregation a ground-breaker, leading the way for further aggregations. We suggest ST_CENTROID, because it consumes points and generates a point, allowing this to not need support for geo_shape geometries, yet.
