Hey,
I want to report an issue with tsfile, specifically its query capabilities.
The two-argument constructor for org.apache.iotdb.tsfile.read.common.Path
that is now available in the apache incubator project still does not allow
proper construction of a path where the measurement name contains dots.
Specifically, the issue is that the two-argument constructor concatenates
the two arguments with a path-separator character (the dot) and then splits
the result again, using the seperator (the dot), instead of just using the
supplied arguments as they are.
This results in the path components being incorrect (device basically runs
to lastIndexOf('.') for the full path) and the query failing.
The rest of tsfile's write/read/query functionality doesn't seem to mind
measurement names that contain dots (think RDF and IRIs) and the intended
query can be run with a minor fix by sub-classing the Path class.
(Unfortunately, Path::init() is also private, so the work-around is not
readily possible.)
Regards,
Marko Friedemann
