+如图所见，前5个小时对数据库的并发压力逐渐增大，写入 TPS 也随之提升，当 TPS 不再增长时，维持并发压力持续测试100小时。

 #### 注释：
 - <a name="bft-raft">BFT-Raft</a>: 在一个 CQL leader 离线的情况下，有两种可能的选择：等待 leader 上线，以保证数据的完整性，或者提拔 follwers 以保证服务可用性；目前是需要一定的人工介入来进行策略选择，这部分仍在迭代中，欢迎任何建议。

+As seen above, the concurrency pressure on the database increased gradually in the first 5 hours, and the write TPS also increased. When the TPS no longer grows, the concurrent pressure is maintained for 100 hours.
