Krisztian Szucs created ARROW-2476:
--------------------------------------
Summary: [Python/Question] Maximum length of an Array created from
ndarray
Key: ARROW-2476
URL: https://issues.apache.org/jira/browse/ARROW-2476
Project: Apache Arrow
Issue Type: Improvement
Reporter: Krisztian Szucs
So the format
[describes|https://github.com/apache/arrow/blob/master/format/Layout.md#array-lengths]
that an array max length is 2^31 - 1, however the following python snippet
creates a 2**32 length arrow array:
{code:python}
a = np.ones((2**32,), dtype='int8')
A = pa.Array.from_pandas(a)
type(A)
{code}
{code}pyarrow.lib.Int8Array{code}
Based the layout specification I'd expect a ChunkedArray of three Int8Array's
with lengths:
[2^31 - 1, 2^31 - 1, 2]
If it's the expectation is there any documentation for it?
