Ivan Daschinskiy commented on IGNITE-11854:
-------------------------------------------
[~dmekhanikov] Currently, serialization-deserialization are fully reworked,
moreover, hashcode caclulation are now much faster due to C module
Here is some benchmarks (put-get) of BinaryObject with 10Mb field
{code:java}
------------------------------------------------ benchmark 'binary_object_get':
1 tests ------------------------------------------------
Name (time in ms) Min Max Mean

{code}
70ms for get and 60ms for put doesn't seems to be infinite, does it? And this
is without partition awareness :)
> 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
> Assignee: Dmitry Melnichuk
> Priority: Major
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> 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.
