@eyalj - you can define the return distinct in the query object.

query = new Query();
query.where = "condition";
query.returnDistinctValues = true);
layer.queryFeatures(query);

Please refer to the API returnDistinctValues

@eyalj  - we have known limitations for this:

* For service-based queries, this parameter applies only if the supportsAdvancedQueries capability of the layer is true.
* Make sure to set returnGeometry to false when returnDistinctValues is true. Otherwise, reliable results will not be returned.

Hope you are comply with these limitations.
