We have added default serializers to the 4.2 series here:
hazelcast/hazelcast#17934

There is a problem with backward compatibility. If a user had CustomSerializer for optional in 4.1, in 4.2 there is no way to use their serializers, and Hazelcast will throw java.lang.IllegalArgumentException: [class java.util.Optional] serializer cannot be overridden

This results in an attempt to access /var/run/secrets/kubernetes.io/serviceaccount/token which while fail in environments where token does n

Currently, the Go client does not support Hazelcast's partition predicate.

We currently don't lint source code of tests which is not nice. The configuration should be placed in the ./test subdir and lint script should be updated in package.json.

For example, to configure the reconnect mode, one has to do the following.

import hazelcast

from hazelcast.config import ReconnectMode


client = hazelcast.HazelcastClient(
    reconnect_mode=ReconnectMode.OFF,
)

We can get rid of the import and extra typing required by also allowing configurations like below

import hazelcast

client = hazelcast.Hazelcas

Hazelcast FlakeID Generator is not available to .NET Client.
