Stepan!
TL/DR: what you got with Python client in your gist is an intended behavior.
Explanation: As per docs, Object array contains of type ID (which is
defaults to -1) and an array of objects.
https://apacheignite.readme.io/docs/binary-client-protocol-data-format#section-object-array
Your gist might be fixed accordingly:
```
from pyignite import Client
from pyignite.datatypes import *
OBJECT_ARRAY_TYPE_ID = -1
OBJECT_ARRAY_CONTENTS = [1, 2]
client = Client()
client.connect('127.0.0.1', 10800)
cache = client.get_or_create_cache("PY_OBJECT_ARRAY")
cache.put(
1,
(OBJECT_ARRAY_TYPE_ID, OBJECT_ARRAY_CONTENTS),
key_hint=IntObject,
value_hint=ObjectArrayObject,
)
# Python output: print(cache.get(1))
# (-1, [1, 2])
```
The situation is similar with Map and Collection, they have types. Types
and type IDs are mostly useless in Python, but I left them for
interoperability reasons. If you think I should kick them out, just let
me know.
The usage of these 3 data types is documented and tested. You can refer
to the table in “Data types” section:
https://apache-ignite-binary-protocol-client.readthedocs.io/en/latest/datatypes/parsers.html
The tests are here:

Hi, everyone
Create new thread to centralize cross compatibility and others common
problems between thin clients
Tying to use Object array to exchange different data between JS, PHP and
Python thin clients
JS and PHP simply can't put any type of arrays
Python can put data, but if you take it, data would be completely
different, maybe during this put process data is changed
Code and output:

I'm tried different data types (string, double, float, complex objects,
just random objects, char, byte, Date), still
How, from my perspective, it should works:
put array of any type and then get this array.
Example: put [1,2,3] -> get [1,2,3] or put [new Date(), new Date()] ->
get [[Date object], [Date object]] (like in java thin client)
Looks like bug in all clients, what you think?
I wanted to try Collections, but i think this type have same problem
