Well, that does only add items to the index before it is finally built and remains after that immutable. It then serializes the index as Java object stream to disk. Just the collection of items though, not the underlying STR-Tree - this will be rebuild each time on startup. But there is no mechanism yet that would write changes made to a mutable R-Tree index to disk then, i.e. it would only be changed in-memory, but the question would be how to make those changes persistent. Re-serializing the index each time the RDF graph is being changed seems to be infeasible as it is somewhat slow for larger indexes and it currently just dumps the whole index. The main problem is just that JTS doesn't provide any on-disk index afaik. -- This is an automated message from the Apache Git Service.
