 | [`tidb_rc_read_check_ts`](/system-variables.md#tidb_rc_read_check_ts-new-in-v600) | Newly added | <ul><li> Optimizes read statement latency within a transaction. 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). If a read request has `tidb_rc_read_check_ts` on, it might not be able to use replica-read. Do not turn on both variables at the same time.</li></ul> |
 | [`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_top_sql_max_meta_count`](/system-variables.md#tidb_top_sql_max_meta_count-new-in-v600) | Newly added | Controls the maximum number of SQL statement types collected by [Top SQL](/dashboard/top-sql.md) per minute. The default value is `5000`. |
-| [`tidb_top_sql_max_time_series_count`](/system-variables.md#tidb_top_sql_max_time_series_count-new-in-v600) | Newly added | Controls how many SQL statements that contribute the most to the load (that is, top N) can be recorded by [Top SQL](/dashboard/top-sql.md) per minute. The default value is `100`. |
+| [`tidb_top_sql_max_meta_count`](/system-variables.md#tidb_top_sql_max_meta_count-span-classversion-marknew-in-v600) | Newly added | Controls the maximum number of SQL statement types collected by [Top SQL](/dashboard/top-sql.md) per minute. The default value is `5000`. |

The default value is `100`. |
 | [`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.  |
