Could you please add test case that CreateTopicsRequestData.CreatableTopic#numPartitions and CreateTopicsRequestData.CreatableTopic#replicationFactor return positive value?

Could you verify that newTopic.configs() will return null if it has no configs

@chia7712 looks like the failed tests in the ci are unrelated.

Author: David Jacot <djacot@confluent.io>
Date:   Wed Jun 12 08:29:50 2024 +0200

    KAFKA-16770; [2/2] Coalesce records into bigger batches (apache#16215)

    This patch is the continuation of apache#15964. It introduces the records coalescing to the CoordinatorRuntime. It also introduces a new configuration `group.coordinator.append.linger.ms` which allows administrators to chose the linger time or disable it with zero. The new configuration defaults to 10ms.

    KAFKA-10199: Enable state updater by default (apache#16107)

    We have already enabled the state updater by default once.
    However, we ran into issues that forced us to disable it again.
    We think that we fixed those issues. So we want to enable the
    state updater again by default.

    KAFKA-15045: (KIP-924 pt. 22) Add RackAwareOptimizationParams and other minor TaskAssignmentUtils changes (apache#16294)

    We now provide a way to more easily customize the rack aware
    optimizations that we provide by way of a configuration class called
    RackAwareOptimizationParams.

    We also simplified the APIs for the optimizeXYZ utility functions since
    they were mutating the inputs anyway.
