My questions is about : 1-) Can objectdb server handle 200.000+ connections at the same time concurrently ? Does it have queue and cache ? 2-) is it dangerous to use that system on many online users ?   kadirbasol Kadir BASOL Having 200,000 concurrent threads is probably a bad idea. Usually

ObjectDB database files are usually smaller than database files of other Database Management Systems (object databases and relational databases) but additional internal compression is still possible. Usually smaller files are also faster because less I/O operations are required and memory cache
