The result of the query is immidiately
streamed back to the client. This operation begins the streaming, in order
to continue the streaming, the client must make use of the More
operation and
finally the Close
operation in order to halt the streaming.
The LogicalPlan
is expected to only contain absolute paths even though
that is unfortunatly not expressed in the types currently.
The result of the query is stored in an output file instead of being returned to the user immidiately.

This operation should return whether a file exists in the filesystem.
This operation lists the names of all the immidiate children of the supplied directory in the filesystem.
