The new release of GeoCouch improves the spatial index building time a lot (up to 10x). This comes from using a new bulk insertion algorithm. The spatial index (an R-tree) is implemented as an append-only data structure — just as CouchDB's B-trees are — which benefits from the nature of bulk insertions by allowing large blocks of the index to be appended at one time.
A new milestone has been reached: GeoCouch is now an extension for CouchDB that can be easily installed with your already running instance of CouchDB. Installing the GeoCouch extension is as easy as using the GeoCouch Git-based source with your existing CouchDB source base (>=1.0.2).
