I've done a bit more digging. This code:
````
df = pd.DataFrame(np.random.randint(10, size=(5, 5)))
table = pa.Table.from_pandas(df)
mem = []
for c in table.columns:
buf = c.chunks[0].buffers()[1]
mem.append((buf.address, buf.size))
sorted(mem)
````
...prints...
````
[(140262915478912, 40),
(140262915479232, 40),
(140262915479296, 40),
(140262915479360, 40),
(140262915479424, 40)]
````
My question is: why are these addresses not 40 bytes apart from each other?
What's in the gaps between the buffers? It's not null bitsets - there's
only one buffer for each column. Thanks -
Nick
