Update group-by algorithms to support decor list #105

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently the decor list in the group-by clause is supported as a hack over the 
grouping key list (decor list is appended to the key list; so the decor list 
will be in the output but not used for the group-by comparison). All group-by 
algorithms in hyracks should be able to accept a list of "decor" attributes.
