If read/write conflicts are more severe, turning this variable on will add additional overhead and latency, causing regressions in performance. The default value is `off`.</li><li> This variable is not yet compatible with [replica-read](/system-variables.md#tidb_replica_read-new-in-v40).

 | [`tidb_sysdate_is_now`](/system-variables.md#tidb_sysdate_is_now-new-in-v600) | Newly added | Controls whether the `SYSDATE` function can be replaced by the `NOW` function. This configuration item has the same effect as the MySQL option [`sysdate-is-now`](https://dev.mysql.com/doc/refman/8.0/en/server-options.html#option_mysqld_sysdate-is-now). The default value is `OFF`. |
 | [`tidb_table_cache_lease`](/system-variables.md#tidb_table_cache_lease-new-in-v600) | Newly added | Controls the lease time of [table cache](/cached-tables.md), in seconds. The default value is `3`. |

 | [`tidb_txn_assertion_level`](/system-variables.md#tidb_txn_assertion_level-new-in-v600) | Newly added | Controls the assertion level. The assertion is a consistency check between data and indexes, which checks whether a key being written exists in the transaction commit process. By default, the check enables most of the check items, with almost no impact on performance.  |
