>             Project: Ignite
>          Issue Type: Bug
>          Components: thin client
>    Affects Versions: 2.7
>            Reporter: Denis Mekhanikov

> The following code hangs indefinitely inside of invocation to {{my_cache.put()}}
> {code:java}
> from pyignite import Client
> arr_len = 3_000_000
> content = bytearray(arr_len)
> for i in range(arr_len):
>     content[i] = i % 256
> client = Client()
> client.connect('127.0.0.1', 10800)
> my_cache = client.get_or_create_cache('my cache')
> my_cache.put("key_bin", content){code}
> While the value is only 3MB in size. Implementation of serialization of primitive arrays
seems to be quadratic in length of the array.
