Placement Driver (PD) contains multiple critical modules to ensure the �→ normal operation of TiDB clusters. As the workload of a cluster �→ increases, the between these modules and �→ ultimately affecting the overall service quality of the cluster. �→ Starting from v8.0.0, TiDB addresses this issue by splitting the TSO �→ and scheduling modules in PD into independently independently deployable �→ microservices. This can significantly reduce the mutual interference �→ between modules as the cluster scales. With this architecture, much �→ larger clusters with much larger workloads 0 码力 |

The maximum concurrency limits for other modules on TiKV, such as storage readpool, coprocessor, and gRPC TiKV Thread CPU moni- tor panel. If there is a bottleneck on the modules, it can be adjusted by increasing the concurrency of the modules. 4.6.1.3.3 Given that TiKV has not yet reached the CPU usage bottleneck might not be obvious to detect in traffic, but still the high QPS might lead to bottlenecks in key modules. Solutions: Firstly, locate the table where hot regions are formed based on the specific business 0 码力 |
