Subject [jira] [Created] (IGNITE-11854) Serialization of arrays of primitives in python thin client is not optimal

-----------------------------------------

             Summary: Serialization of arrays of primitives in python thin client is not optimal
                 Key: IGNITE-11854
                 URL: https://issues.apache.org/jira/browse/IGNITE-11854
             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.
