auto-retry by default, also passes. Finally, TiDB has a theoretical dependence on CLOCK_MONOTONIC_RAW for safety, but we have not yet observed anomalies due to clock skew, possibly due to tooling limitations. PingCAP actually enforce them. 2 Test Design Jepsen is a distributed systems testing toolkit, and has found safety and liveness issues in dozens of databases. With Jepsen, one runs a real distributed system, rather workloads with fixed re- quest rates. We also note that Jepsen takes an experi- mental approach to safety verification: we can prove the presence of bugs, but not their absence. While we make extensive efforts

*TiDBSqlTx) Rollback() error { defer tx.conn.Close() return tx.Tx.Rollback() } To ensure thread safety, you can use the mysqlclient driver to open multiple connections that are not shared between threads it will not pick up from the checkpoint, but will report an error and quit the task. To ensure the safety of the imported data, you must resolve these errors by using the tidb-lightning-ctl command before Use at least three AZs in case one AZ fails. • Deploy TiDB in at least three regions in case data safety issue occurs in one region. The native Raft protocol does not have good support for an even number

To ensure the safety of the imported data, you must resolve these errors by using the tidb-lightning-ctl command before nodes in the cluster fail, the cluster can still be available. On this basis, to further ensure data safety, TiDB provides the Backup & Restore (BR) feature as the last resort to recover data from natural
