Starting from v8.0.0, TiDB provides the `TIDB_INDEX_USAGE` table. You can use `TIDB_INDEX_USAGE` to get the usage statistics of all indexes on the current TiDB node. By default, TiDB collects these index usage statistics during SQL statement execution. You can disable this feature by turning off the [`instance.tidb_enable_collect_execution_info`](https://docs.pingcap.com/tidb/v8.0/tidb-configuration-file#tidb_enable_collect_execution_info) configuration item or the [`tidb_enable_collect_execution_info`](/system-variables.md#tidb_enable_collect_execution_info) system variable.

- Starting from TiDB 5.2, to improve system security, it is recommended (but not mandatory) to encrypt the transport layer for connections from clients. TiDB provides the Auto TLS feature to automatically configure and enable encryption in TiDB. To use the Auto TLS feature, before the TiDB upgrade, set [`security.auto-tls`](/tidb-configuration-file.md#auto-tls) in the TiDB configuration file to `true`.

- Support the `caching_sha2_password` authentication method to make migration from MySQL 8.0 easier and to improve security.
