> GSoC 2025 - Apache Seata(Incubating): Extend multi-raft cluster mode
> ---------------------------------------------------------------------
>
> Key: GSOC-274
> URL: https://issues.apache.org/jira/browse/GSOC-274
> Project: Comdev GSOC
> Issue Type: Wish
> Reporter: Jianbin Chen
> Priority: Major
> Labels: Seata, gsoc2025, mentor
>
> h4. Description
> *Synopsis*
> The current Apache Seata Server supports the Raft cluster mode, but the
> performance and throughput of the cluster are significantly limited due to
> the single leader in a single Raft group. Therefore, the goal is to extend
> Seata Server to support multi-raft capability.
>
> *Benefits to Community*
> Due to the characteristics of Raft, requests are processed on the leader node
> and the results are submitted to the followers through the Raft consensus
> protocol. As a result, a significant amount of computational load is placed
> on the leader node, while followers only need to receive the final computed
> result. This causes the CPU, memory, and other metrics of the leader to be
> much higher than those of the followers. Additionally, the throughput of a
> single leader is limited by the machine configuration of the highest-spec
> node in the cluster, making it difficult to balance the traffic effectively.
> Therefore, supporting multi-raft would make the load distribution more
> balanced across all nodes in the cluster, improving throughput and
> performance, while also reducing the waste of machine resources.
>
> *Deliverables*
> The expected delivery goal is to apply the multi-raft capability of the
> sofa-jraft component to Seata Server through detailed learning and practice
>
> The step expected are the following:
> * Learning and using the sofa-jraft component
> * Understanding and practicing the transaction grouping capability in Seata
> * Gaining a certain level of understanding of Seata's communication protocol
> * Gaining a certain level of understanding of Seata's storage model,
> especially the Raft mode
> * Ensuring compatibility between different versions
> *Useful links*
