OrientDB slow write

Question

OrientDB official site says:

On common hardware stores up to 150.000 documents per second, 10 billions of documents per day. Big Graphs are loaded in fe

Answer 1

Read the documentation first on how to achive the best performance!

Few tips:

-> Do NOT instantiate ODocument always:

  final ODocument doc;
  for (...) {
    doc.reset();
    doc.setClassName("Class");
    // Put data to fields
    doc.save();
  }

-> Do NOT rely on System.currentTimeMillis() - use perf4j or similar tool to measure times, because the first one measures global system times hence includes execution time of all other programs running on your system!

Answer 2

You can achieve that by using 'Flat Database' and orientdb as an embedded library in java see more explained here http://code.google.com/p/orient/wiki/JavaAPI

what you use is server mode and it sends many requests to orientdb server, judging by your benchmark you got ~10 000 inserts per seconds which is not bad, e.g I think 10 000 requests/s is very good performance for any webserver (and orientdb server actually is a webserver and you can query it through http, but I think java is using binary mode)

Answer 3

The numbers from the OrientDB site are benchmarked for a local database (with no network overhead), so if you use a remote protocol, expect some delays.

As Krisztian pointed out, reuse objects if possible.
