Re: Potential student projects
There’s always more work to be done in Geospatial, e.g. https://issues.apache.org/jira/browse/CALCITE-2031 <https://issues.apache.org/jira/browse/CALCITE-2031>. The easy part is to create scalar (row-at-a-time) implementations of spatial functions, but the real fun starts when you transform queries to use materialized views (“indexes”). Until now, everything has been on rectangular grids and space-filling curves (i.e. assuming flat-earth) but indexing using Uber H3  or Google S2 would be challenging and cutting-edge.
