Piping bzip2 output into tdbloader2 (apache-jena) gives “File does not exist”
I want to pipe the output from bzip2 and use it as an input to fill a TDB database using tbdloader2 from apache-jena-3.9.0.
I already found
Generating TDB Dataset from archive containing N-TRIPLES files
but the proposed solution there did not work for me.
bzip2 -dc test.ttl.bz2 | tdbloader2 --loc=/pathto/TDBdatabase_test -- -
produces

20:08:01 INFO Data file 1: /home/user/-
File does not exist: /home/user/-

unpacking the bz2 file manually and then adding it works fine:
bzip2 -d test.ttl.bz2
tdbloader2 --loc=/pathto/TDBdatabase_test test.ttl
Would be great if someone could point me in the right direction.

tdbloader2 accepts bz2 compressed files on the command line:
tdbloader2 --loc=/pathto/TDBdatabase_test test.ttl.bz2
It doesn't accept input from a pipe - and if it did, then it would not know the syntax is Turtle which it gets from the file extension.

bz2 and gz are a single file compression tools; zip is an archive where the individual entries have separate names. c.f. tar The names matter for reading files to get the syntax. zip files could be supported; it is unpacking and reading each file but the base URI is going to be weird. (yes, gz can have several files, but it isn't an archive as such.)
