Regardless of subj: does call getOutputMetadata() cause network round trip?
Sometimes but typically not. If appropriate metadata was not pefetched by prepare() call (see last parameter flags, family of PREPARE_PREFETCH_* constants) - yes, there will be one roundtrip. Afterwards metadata is cached and may be requested once again w/o use of network.
