<div id="body1587865451575"><p id="kafka-faq-200426025__p11227976415">Kafka manages messages by partition. If there are too many partitions, message creation, storage, and retrieval will be fragmented, affecting the performance and stability. If the total number of partitions of topics reaches the upper limit, you cannot create more topics.</p>
