Hello,
I created a HDF5 file containing an array with the following dimension
(5000,1). I notice a big difference file size between the array creation
with createCArray and createEArray.
For creation of the table with createCArray, i use this script :
h5ft=openFile('test_carray.h5','w')
ca=h5ft.createCArray(h5ft.root,"foo",Float32Col(),(5000,1),"carray test")
for ii in range(5000):
ca[ii][0]=1.0
ca.flush()
h5ft.close()
For creation of the table with createEArray, I use this script:
h5ft=openFile('test_earray.h5','w')
ca=h5ft.createEArray(h5ft.root,"foo",Float32Col(),(0,1),"earray test")
for ii in range(5000):
ea.append([[1.0]])
ea.flush()
h5ft.close()
the size files are :
1.7Ko for test_carray_file.h5
29Ko for test_earray_file.h5
I don't understand why the last file is bigger than the first ? do I make a
mistake in my scripts ?
Thanks,
Didier
