- jemalloc do not call clock_gettime() that frequently

- the difference is CLOCK_MONOTONIC 20ns and CLOCK_MONOTONIC_COARSE 4ns

As part of every pull request which adds a new feature, it is necessary to write documentation for it. If you'd like to preview your documentation changes the instructions for how to build the documentation page locally are available in the README.md file [here](https://github.com/ClickHouse/clickhouse-docs). When adding a new function to ClickHouse you can use the template below as a guide:

# MySQL Interface
|
||||
|
||||
ClickHouse supports the MySQL wire protocol. This allow tools that are MySQL-compatible to interact with ClickHouse seamlessly (e.g. [Looker Studio](../integrations/data-visualization/looker-studio-and-clickhouse.md)).
|
||||
ClickHouse supports the MySQL wire protocol. This allows certain clients that do not have native ClickHouse connectors leverage the MySQL protocol instead, and it has been validated with the following BI tools:
|
||||
|
||||
- [Looker Studio](../integrations/data-visualization/looker-studio-and-clickhouse.md)
|
||||
- [Tableau Online](../integrations/tableau-online)
|
||||
- [QuickSight](../integrations/quicksight)
|
||||
|
||||
If you are trying other untested clients or integrations, keep in mind that there could be the following limitations:
|
||||
|
||||
- SSL implementation might not be fully compatible; there could be potential [TLS SNI](https://www.cloudflare.com/learning/ssl/what-is-sni/) issues.
|
||||
- A particular tool might require dialect features (e.g., MySQL-specific functions or settings) that are not implemented yet.
|
||||
|
||||
If there is a native driver available (e.g., [DBeaver](../integrations/dbeaver)), it is always preferred to use it instead of the MySQL interface. Additionally, while most of the MySQL language clients should work fine, MySQL interface is not guaranteed to be a drop-in replacement for a codebase with existing MySQL queries.
|
||||
|
||||
If your use case involves a particular tool that does not have a native ClickHouse driver, and you would like to use it via the MySQL interface and you found certain incompatibilities - please [create an issue](https://github.com/ClickHouse/ClickHouse/issues) in the ClickHouse repository.

|

The fewer and the larger the equivalence classes are, the higher the degree of freedom when re-shuffling rows.
|

||||
The heuristics applied to find the best row order within each equivalence class is suggested by D. Lemir, O. Kaser in [Reordering columns for smaller indexes](https://doi.org/10.1016/j.ins.2011.02.002) and based on sorting the rows within each equivalence class by ascending cardinality of the non-primary key columns.

It performs three steps:
|

1. Find all equivalence classes based on the row values in primary key columns.
|

2. For each equivalence class, calculate (usually estimate) the cardinalities of the non-primary-key columns.

## Reading nested subcolumns from Array
|
||||
|
||||
If nested type `T` inside `Array` has subcolumns (for example, if it's a [named tuple](./tuple.md)), you can read its subcolumns from an `Array(T)` type with the same subcolumn names. The type of a subcolumn will be `Array` of the type of original subcolumn.
|
||||
|
||||
**Example**
|
||||
|
||||
```sql
|
||||
CREATE TABLE t_arr (arr Array(Tuple(field1 UInt32, field2 String))) ENGINE = MergeTree ORDER BY tuple();
|
||||
INSERT INTO t_arr VALUES ([(1, 'Hello'), (2, 'World')]), ([(3, 'This'), (4, 'is'), (5, 'subcolumn')]);
