Hi,

Are you using your own MetadataProvider or a given one (LiteralBasedProvider or similar is needed)?
Have you created your table using as schema an array of field names?

About bandwidth note that item/field names never go through the stream.


PS: I noticed that this tutorial use the loadEngineMinimal method. Please upgrade to the new createEngine method as loadEngineMinimal is a deprecated method (I will update this tutorial as soon as possible)
PPS: Updated!
