Metadata.Dataset vs asterix.Dataset

[Steven Jacobs]

Hi all,
Right now when we compile an AQL FLWOR vs an SQL SELECT we get two
different function signatures for "Dataset"

SQL calls "asterix.Dataset" while AQL calls "Metadata.Dataset"

Does anyone know why these are distinct?

To see an example, look at the rewrittenResult in
QueryTranslator.rewriteCompileQuery for the following:

  for $x in dataset TwitterUsers
  return $x;


vs

  select * from TwitterUsers;
