[Pytables-users] pytables compatibility with h5tb

[Milad F. <ic...@gm...>]

Hello:

I have been using pytables to create HDF5 files which are then read in
by another code, written in C++ which uses the 1.8.1 version of the
HDF5 library. Everything was going well until I made a table with 1
record in pytables, then appended to the table in the C++ code using
the H5TB interface. No matter how many records I appended in C++, only
2 records would actually be stored - the original one I made with
pytables and the last record I appended in C++. If I create the table
in C++, I can append to it without problems...

My main question is: Is it OK to write/modify HDF5 tables made with
pytables in C/C++? And to what extent are HDF5 files generated in
pytables usable by other HDF5 tools that don't use pytables?

I have a feeling that there can be incompatibilities because tables
generated by pytables have a VERSION attribute set to 2.6, while those
generated in C/C++ with hdf5 v1.8.1 have a VERSION attribute set to
2.0 (although I am not sure exactly what this version number means...)


Thanks
