    I'm trying to overwrite the pandas dataframe in hdf5 file. Each time I do this, the file size grows up while the stored frame content is the same. If I use mode='w' I lost all other records. Is this a bug or am I missing something?

    import pandas
    df = pandas.read_csv('1.csv')
    for i in range(100):
    store = pandas.HDFStore('tmp.h5')
    store.put('TMP', df)
    store.close()


    The tmp.h5 grows in size.
