Subject GiST indexes anyone?
Date Wed, 15 Sep 2004 15:26:58 GMT

(* I originally posted this to the derby-users group but that would appear 
to be the wrong arena. *)

Barrodale Computing Services are rather excited by the  open sourcing of 
Cloudscape (Derby).
Specifically, we are interested in exploiting/augmenting Cloudscape's 
spatial capabilities. We have implemented spatial datatypes and indexes for 
the Informix and postgreSQL in the past. But if we understand correctly, 
Cloudscape does not currently support spatial types nor indexing strategies.
Certainly nothing on the features page suggests this.

That being said, we heard rumours of a GiST "experiment" underway in 
Cloudscape.  If the GiST code could be made available, this would greatly 
facilitate the development, ultimately, of spatial indexes, including but 
not necessarily limited to R-tree indexes.  With a proper spatial index, 
Cloudscape could be applied to a much more interesting set of problems, 
particularly in areas related to GIS.
