Hello Jim,
The major hurdle here is exposing 7Zip to HDF5. Luckily it appears as if
this may have been taken care of for you by the HDF-group already [1]. You
should google around to see what has already been done and how hard it is
to install. The next step is to expose this as a compression o
I love the index function and promote the internal use of PyTables at my
company. The availability of a indexed method to speed the search is the main
reason why.
We are a mixed shop using c++ to create H5 (just for the raw speed … need to
keep up with streaming data) End users start with py
I would like to squeeze out as much compression as I can get. I do not mind
spending time on the front end as long as I do not kill my read performance.
Seems like 7Zip is well suited to my data. Is it possible to have 7Zip used as
the native internal compression for a pytable?
If not now ha
Thanks Anthony,
This also did the trick:
import tables
h5f_in = tables.open('CO.h5)
tbl_in = h5f_in.root.CO.DATA
h5f_out = tables.openFile('test.h5', 'w')
g = h5f_out.createGroup('/','CO')
ot = tbl.copy(newparent=g)

Hey Aquil,
I think File.copyNode() [1] with the newparent argument as group on another
file will do what you want.
Be Well

I create the tables in an HDF5 file from three different python processes. I
needed to modify one of the processes, but not the others. Is there an easy way
to copy the two tables that did not change to the new file?
