Hi Peter,
Thank you for giving a try looking at it.
This is the test code:
static void TestNeo4j(int MaxDegreeOfParallelism)
{
Teva.Common.Data.Neo4j Client = new
Common.Data.Neo4j("127.0.0.1", "7474");
System.Diagnostics.Stopwatch Stopwatch = new
System.Diagnostics.Stopwatch();
Stopwatch.Start();
var RootNode =
(Neo4jRestNet.Core.Node)Client.GetScalar("x=g.addVertex(['Root':'Root']);x;");
object RootID = RootNode.Id;
Console.WriteLine("Root: " + RootID + " (" +
Stopwatch.ElapsedMilliseconds + "ms)");
Stopwatch.Restart();
int NodesCount = 100;
int ReadsCount = 100;
Parallel.For(0, NodesCount, new ParallelOptions {
MaxDegreeOfParallelism = MaxDegreeOfParallelism }, i =>
{
var Properties = new Neo4jRestNet.Core.Properties();
Properties.SetProperty("Name", "Name_" + i);
Properties.SetProperty("Value", "Value_" + i);
Client.Execute("x=g.addVertex(['Name':", new
GremlinParameter("Name_" + i), ",'Value':", new GremlinParameter("Value_" +
i), "]);g.addEdge(g.v(", new GremlinParameter(RootID), "), x,
'Instance');");
});
Console.WriteLine("Created " + NodesCount + " nodes (" +
Stopwatch.ElapsedMilliseconds + "ms)");
Stopwatch.Restart();
#region Read / Count
Parallel.For(0, ReadsCount, new ParallelOptions {
MaxDegreeOfParallelism = MaxDegreeOfParallelism }, i =>
{
var Count = Client.GetScalar("g.v(", new
GremlinParameter(RootID), ").out('Instance').count()");
});
#endregion
Console.WriteLine("Counted " + ReadsCount + " x " + NodesCount
+ " nodes (" + Stopwatch.ElapsedMilliseconds + "ms)");
Stopwatch.Restart();
#region Read / Instances
Parallel.For(0, ReadsCount, new ParallelOptions {
MaxDegreeOfParallelism = MaxDegreeOfParallelism }, i =>
{
var Result = Client.GetArray("g.v(", new
GremlinParameter(RootID),
").out('Instance').transform{['ID':it.id,'SchemaID':it._().in('Instance').id.next()]}");
foreach (Dictionary<string, object> Item in Result)
{
object ID = Item["ID"];
object SchemaID = Item["SchemaID"];
}
});
Console.WriteLine("Read " + ReadsCount + " x " + NodesCount + "
nodes (" + Stopwatch.ElapsedMilliseconds + "ms)");
Stopwatch.Restart();
#endregion
}
