RocketMQ 5.0 introduces a brand-new 5.x SDK based on the gRPC protocol. The new SDK version offers a more lightweight framework and better multilingual support. We highly recommend that you use this version. Moreover, TDMQ for RocketMQ 5.x series continues to support the access through the 4.x SDK for existing businesses.
