Description

The following code hangs indefinitely inside of invocation to my_cache.put()

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)

While the value is only 3MB in size. Implementation of serialization of primitive arrays seems to be quadratic in length of the array.
