[jira] [Created] (CALCITE-5281) Implement geometry set returning functions (SRF)

Bertil Chapuis created CALCITE-5281:
---------------------------------------

             Summary: Implement geometry set returning functions (SRF)
                 Key: CALCITE-5281
                 URL: https://issues.apache.org/jira/browse/CALCITE-5281
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Bertil Chapuis


The idea is to implement set returning functions, such as ST_Explode in H2GIS and ST_Dump in PostGIS. Is the Uncollect class a good starting point?
