Results from Fabric Timing tests. I'm trying to establish a performance baseline, and generally, to better understand the available methods for executing Gremlin scripts from outside the JVM.

The tests each execute a simple g Gremlin script (to obtain the graph object) using different methods. My testing scenario uses Titan (+ local Berekely DB) on a separate machine in the same local network. The RexProClient library for these tests was built in Release mode.

Update (2013-06-07): I have improved the tests based on suggestions from Daniel. See updated results below.

First step: change this StandardTypeMaker line to use the And operator between isUnique:

if ((isUnique[0] && isUnique[1]) && !primaryKey.isEmpty()) throw new IllegalArgumentException("Cannot define a primary key on a unique type")

This allows an IN-unique or OUT-unique edge to use Titan's vertex-centric indexing. Note the unique(OUT) in the example below:

function buildJiraMarkdown(card) {
    var jira =
        "{panel}\n"+
        "h3. [" + card.name + "|" + card.shortUrl + "]\n" +
        card.desc + "\n\n" +
        "*Labels:* ";

    for (var i = 0; i < card.labels.length; ++i) {
        var label = card.labels[i];
        var c = label.color;
