Properly use NavMeshQuery

Hi there. I have a lot of units an army with formations and want them move on navmesh. I tried look into Nordeus demo , but got more questions. So what better way? Should i use NavMeshQuery per formation or per unit or some another division. Why NavMeshQuery used in Job and not parallel Job? How can i use it at all

Like this:

Code (CSharp):

1.  
2. public void Execute(int index)
3. {
4.        var start = NavMeshQuery.MapLocation(UnitPositionComponentArray[index].Value, Vector3.one * 0.5f, 0);
5.        var end = NavMeshQuery.MapLocation(MinionPathDataArray[index].TargetPosition, Vector3.one * 0.5f, 0);
6.        var status = NavMeshQuery.BeginFindPath(start, end);
7.  
8.        NavMeshQuery.UpdateFindPath(256, out int performed);
9.  
10.        status = NavMeshQuery.EndFindPath(out int polySize);
11.  
12.        var poligons = new NativeArray<PolygonId>(polySize, Allocator.Temp);
13.        NavMeshQuery.GetPathResult(poligons);
14.  
15. }

Checking "status" and use "end" like a target point for units? And there is another way when you just use NavMeshAgent where set target and Unit walk themself to target. So i got this "end" point and should use some MovementSystem and move units with my own system to target? And if its way how units will avoid objects and e.t.c. ?

 

Any tips?
