can i use bdb(berkeley db) file created by c implementation (python bsddb) by oracle berkeley db java edition?

Question

Hi,

I have a berkeley db file (*.bdb) which is created by the C implementation(python bsddb module). Is it possible to read this file by a pure java implementation of Berkeley Db? I tried to read it using berkeley db java edition (je) but could not. je throws out an exception saying that it could not detect the berkeley database. Are berkeley db files not inter operable across different implementations? If so, why?

Answer 1

I haven't researched the definite answer, but I have the same experience. A database created with pythons bdb, and also accessible with the cli utils, is not detected at all by the Java API. The reverse was also true.

Answer 2

No.

According to the Berkeley DB Java Edition FAQ, Berkeley DB and Berkeley DB Java Edition are not compatible with one another because they have a different file layout structure.
