Wes McKinney closed ARROW-5907.
-------------------------------
Resolution: Won't Fix
I don't think it makes sense to implement the buffer protocol on Array classes
> [Python] base64 support of bytes-like
> -------------------------------------
>
> Key: ARROW-5907
> URL: https://issues.apache.org/jira/browse/ARROW-5907
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Python
> Affects Versions: 0.14.0
> Reporter: Litchy
> Priority: Major
>
> Currently pyarrow could not be encoded by base64:
> {code}
> t = numpy.arange(25, dtype=np.float64)
> a = pyarrow.array(t)
> s1 = base64.b64encode(t) # this works
> s2 = base64.b64encode(a)
> {code}
> gives "a bytes-like object is required not 'pyarrow.lib.DoubleArray'"
> Because it is not bytes-like
> A possible scenario could be if we want to push data(like ndarray) to Redis
> in Python and get it from other language like Java. Arrow could be used to
> interact between Python and Java using Array of Arrow.
> Adding this feature would support some in-queue and out-queue operations like
> Redis
