Hi Jody, Gabriel, Kevin I have been porting all modules to use the resources system consistently and only use files when necessary (usually external library). I still stumbled upon two minor questions/issues I wanted to discuss.
1. Usage of the "data" directory. At the moment the import from data directory -> jdbc store ignores the "data" directory. In a clustered environment, this directory thus remains instance specific, and it would be up to the user to refer to shared files. At this moment, there is no reason why we couldn't include the data dir in the jdbcstore and cache it before loading the geotools datastore. This is actually what my modified version of the rest service already does because it uses resources everywhere. Another idea, was to program the jdbcstore to return file based resources only when the "data" directory is used, so that it definitely will never store those files in the database unnecessarily. 2. In the jdbcstore, should the children of a directory be cached when dir() is called? The DataDirectory class uses the dir() method to know the root of the data directory, causing the whole data directory to be cached at once multiple times unnecessarily, since the root dir is usually requested just to know the path for some reason (all code where it actually needs files in the data dir, have been replaced by resources). We now always want to use resources as long as possible, only calling file() at the last moment if necessary. As a consequence the dir() method is actually hardly used for the purpose or getting all the files inside that dir. I would suggest on calling dir() only to create the dir if it doesn't exist yet and not cache its children. There is only one part of code left where that would pose a problem, the community module "validation", which passes on a whole dir to its geotools counterpart. This however could be changed in the geotools module to pass on a collection of files instead. After this change, I wonder if we should make a doc page on the proper practices of using the Resource API in order to be clustering-safe.
