diaohancai opened a new issue, #288:
URL: https://github.com/apache/incubator-hugegraph-computer/issues/288
### Feature Description (功能描述)
`ComputerOptions.INPUT_FILTER_CLASS` default value is `DefaultInputFilter`.
`org.apache.hugegraph.computer.core.input.filter.DefaultInputFilter`
```java
public class DefaultInputFilter implements InputFilter {
@Override
public Vertex filter(Vertex vertex) {
vertex.properties().clear();
return vertex;
}
@Override
public Edge filter(Edge edge) {
edge.properties().clear();
return edge;
}
}
```
Load all properties first, and clear.
Could we specify some properties when loading vertices or edges? May could
improve performance.
`org.apache.hugegraph.computer.core.input.hg.HugeVertexFetcher`
```java
@Override
public Iterator<Vertex> fetch(InputSplit split) {
Shard shard = toShard(split);
return this.client().traverser().iteratorVertices(shard,
this.pageSize());
}
```
But it seems that the traverser api does not yet support specifying some
properties to load vertices or edges on the server side.
