> The current implementation for generating database keys in the kiwi-triplestore is based on either database sequences (safe method, but slow) or in-memory sequences (fast method, but does not allow concurrent database access). We should also add an implementation that is both fast and reasonably safe by generating random long IDs using a reliable algorithm. For example, we could use UUID.getLeastSignificantBits() to create this ID.
