    Tencent TDMQ for CKafka team has further fine-tuned the service performance to eliminate complex parameter configuration and offer higher performance.
    CKafka supports upgrade and Ascending via UI operations and is backed by a powerful IaaS layer, delivering 10% to 20% higher production capabilities than Apache Kafka.
