[jira] [Updated] (ARROW-5907) base64 support of bytes-like

["Joris Van den Bossche (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-5907?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joris Van den Bossche updated ARROW-5907:
-----------------------------------------
    Description: 
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
