URL: https://github.com/apache/beam/issues/21198
Apache Beam is using google-cloud-spanner version 1.19.1, while current
version of google-cloud-spanner is 3.11.1.
I was attempting to use ReadFromSpanner when I ran into a ValueError - it
was getting a type code 11 from Spanner and couldn't parse it.
Here is (some) relevant code from v3.11.1 of Spanner:
```
class TypeCode(proto.Enum):
r"""``TypeCode`` is used as part of [Type][google.spanner.v1.Type]
to
indicate the type of a Cloud Spanner value.
Each legal value of a type can be encoded
to or decoded from a JSON
value, using the encodings described below. All Cloud Spanner values
can be ``null``, regardless of type; ``null``\ s are always encoded
as a JSON ``null``.
"""
TYPE_CODE_UNSPECIFIED = 0
BOOL = 1
INT64 = 2
FLOAT64 = 3
TIMESTAMP
= 4
DATE = 5
STRING = 6
BYTES = 7
ARRAY = 8
STRUCT = 9
NUMERIC
= 10
JSON = 11
```
and the same from v1.19.1:
```
_sym_db.RegisterEnumDescriptor(_TYPECODE)
TypeCode = enum_type_wrapper.EnumTypeWrapper(_TYPECODE)
TYPE_CODE_UNSPECIFIED
= 0
BOOL = 1
INT64 = 2
FLOAT64 = 3T
IMESTAMP = 4
DATE = 5
STRING = 6
BYTES = 7
ARRAY = 8
STRUCT
= 9
NUMERIC = 10
```
There is no support for type code 11, aka JSON in Apache Beam right now.
