Alternatively, VTAdmins dependencies could have vulnerabilities

grows, the decision-making leaders need to understand the business status of the entire company to make decisions in time. In this case, the company needs to aggregate the scattered data into the same system region-split-size to set Re- gions to a larger size. This can effectively reduce the number of Regions, make Regions easier to manage, and improve the cluster performance and stability. User document, #11515 dynamically In earlier TiDB versions, after modifying a configuration item, you must restart the cluster to make the modification effective. This might interrupt online services. To address this issue, TiDB v6.1

In this case, the company needs to aggregate the scattered data into the same system recovery (PITR) along with cdclog. Since v5.4.0, cdclog-based PITR and cdclog are no longer supported. • Make the behavior of setting system variables to the “DEFAULT” more MySQL- compatible #29680 • Set the Engine in v5.4.0 is not compatible with previous versions. Before upgrading the cluster, you need to make sure that Raft Engine on all TiKV nodes is disabled. It is recommended to use Raft Engine only in

To make the IDs incremental among multiple TiDB servers, you can use the AUTO_INCREMENT MySQL compatibility TiDB This document briefly introduces how to use TiDB’s CURD SQL. 4.2.2.1 Before you start Please make sure you are connected to a TiDB cluster.
