+Reading Line Delimited JSON
+===========================
+
+Arrow has builtin support for line-delimited JSON.
+Each line represents a row of data as a JSON object.
+
+Given some data in a file where each line is a JSON object
+containing a row of data:
+
+.. testcode::
+
+ import tempfile
+
+ with tempfile.NamedTemporaryFile(delete=False, mode="w+") as f:
+ f.write('{"a": 1, "b": 2.0, "c": 1}\n')
+ f.write('{"a": 3, "b": 3.0, "c": 2}\n')
+ f.write('{"a": 5, "b": 4.0, "c": 3}\n')
+ f.write('{"a": 7, "b": 5.0, "c": 4}\n')
Review comment:
I think that when nulls change the behaviour of something and you need
special code to deal with them we should have dedicated recipes. But in this
case having nulls in the data shouldn't change how you deal with it, so I don't
think there is much value in adding nulls
