 [SSL 'strict' option](../server-configuration-parameters/settings.md#server_configuration_parameters-openssl) enables mandatory certificate validation for the incoming connections. In this case, only connections with trusted certificates can be established. Connections with untrusted certificates will be rejected. Thus, certificate validation allows to uniquely authenticate an incoming connection. `Common Name` field of the certificate is used to identify connected user. This allows to associate multiple certificates with the same user. Additionally, reissuing and revoking of the certificates does not affect the ClickHouse configuration.

+# Memory overcommit
+
+Memory overcommit is an experimental technique intended to allow to set more flexible memory limits for queries.
+
+The idea of this technique is to introduce settings which can represent guaranteed amount of memory a query can use.
+When memory overcommit is enabled and the memory limit is reached ClickHouse will select the most overcommitted query and try to free memory by killing this query.
+
+When memory limit is reached any query will wait some time during attempt to allocate new memory.
+If timeout is passed and memory is freed, the query continues execution.
+Otherwise an exception will be thrown and the query is killed.
+
+Selection of query to stop or kill is performed by either global or user overcommit trackers depending on what memory limit is reached.
+If overcommit tracker can't choose query to stop, MEMORY_LIMIT_EXCEEDED exception is thrown.
+
+## User overcommit tracker
+
+User overcommit tracker finds a query with the biggest overcommit ratio in the user's query list.
+Overcommit ratio for a query is computed as number of allocated bytes divided by value of `memory_overcommit_ratio_denominator` setting.
+
+If `memory_overcommit_ratio_denominator` for the query is equals to zero, overcommit tracker won't choose this query.
+
+Waiting timeout is set by `memory_usage_overcommit_max_wait_microseconds` setting.
+
+**Example**
+
+```sql
+SELECT number FROM numbers(1000) GROUP BY number SETTINGS memory_overcommit_ratio_denominator=4000, memory_usage_overcommit_max_wait_microseconds=500
+```
+
+## Global overcommit tracker
+
+Global overcommit tracker finds a query with the biggest overcommit ratio in the list of all queries.
+In this case overcommit ratio is computed as number of allocated bytes divided by value of `memory_overcommit_ratio_denominator_for_user` setting.
+
+If `memory_overcommit_ratio_denominator_for_user` for the query is equals to zero, overcommit tracker won't choose this query.
+
+Waiting timeout is set by `global_memory_usage_overcommit_max_wait_microseconds` parameter in the configuration file.

 The second version (with the `max_size` parameter) limits the size of the resulting array to `max_size` elements. For example, `groupArray(1)(x)` is equivalent to `[any (x)]`.

 In some cases, you can still rely on the order of execution. This applies to cases when `SELECT` comes from a subquery that uses `ORDER BY`.

+返回两个整数值的位表示之间的 [Hamming Distance](https://en.wikipedia.org/wiki/Hamming_distance)。可与 [SimHash](../../sql-reference/functions/hash-functions.md#ngramsimhash) 函数一起使用，用于检测半重复字符串。距离越小，这些字符串就越有可能相同。
+
+**语法**
+
+``` sql
+bitHammingDistance(int1, int2)
+```
+
+**参数**
+
+-   `int1` — 第一个整数值。类型为[Int64](../../sql-reference/data-types/int-uint.md)。
+-   `int2` — 第二个整数值。类型为[Int64](../../sql-reference/data-types/int-uint.md)。
+
+**返回值**
+
+-   汉明距离。
+
+类型为： [UInt8](../../sql-reference/data-types/int-uint.md)。
+
+**示例**
+
+查询语句：
+
+``` sql
+SELECT bitHammingDistance(111, 121);
+```
+
+结果：
+
+``` text
+┌─bitHammingDistance(111, 121)─┐
+│                            3 │
+└──────────────────────────────┘
+```
+
+使用[SimHash](../../sql-reference/functions/hash-functions.md#ngramsimhash)函数:
+
+``` sql
+SELECT bitHammingDistance(ngramSimHash('cat ate rat'), ngramSimHash('rat ate cat'));
+```
+
+结果：
+
+``` text
+┌─bitHammingDistance(ngramSimHash('cat ate rat'), ngramSimHash('rat ate cat'))─┐
+│                                                                            5 │
+└──────────────────────────────────────────────────────────────────────────────┘
