Good questions. The javadocs don't say, but normally DataStore implementations are thread safe, and so are feature source implementations. GeoServer hits them with many threads concurrently without issues normally, but the index gets created as we configure the shapefile as a new layer, at that point only one user (the administrator) is accessing the store. Patches to improve thread safety are welcomed Cheers Andrea -- ------------------------------------------------------- Ing. Andrea Aime GeoSolutions S.A.S.
