> What makes something appropriate as an extension type rather than a basic supported type? GEOMETRY is currently supported natively, which seems to be simply a binary blob with a metadata CRS string. Is the problem that adding such types is cumbersome? Yes, mainly the fact that adding new types is cumbersome, so there is a trade-off between how useful we expect the type to be to the broader community. The other questions which comes into play are things like if stats are important, how well an extension type would work in this context (I forget if this design addresses that issue). IMO, GEOMETRY might have been considered for an extension type if we had this facility. As a datapiont, in the Arrow project most new types have been added as extension types I believe. -- This is an automated message from the Apache Git Service.
