[Pytables-users] Clear chunks from CArray

[Giovanni L. C. <glc...@gm...>]

Hello all,

is there a way to clear out a chunk from a CArray? I noticed that setting the 
data to zero actually takes disk space, i.e.

***
from tables import open_file, BoolAtom

h5f = open_file('test.h5', 'w')
ca = h5f.create_carray(h5f.root, 'carray', BoolAtom(), shape=(1000,1000), 
chunkshape=(1,1000))
ca[:,:] = False
h5f.close()
***

The resulting file takes 249K ...

Best,
