Annoy currently supports `L2Distance` and `cosineDistance` as distance function `Distance`. If no distance function was specified during
index creation, `L2Distance` is used as default. Parameter `NumTrees` is the number of trees which the algorithm creates (default if not
specified: 100). Higher values of `NumTree` mean more accurate search results but slower index creation / query times (approximately
linearly) as well as larger index sizes.
Annoy currently supports two distance functions:
- `L2Distance`, also called Euclidean distance, is the length of a line segment between two points in Euclidean space
([Wikipedia](https://en.wikipedia.org/wiki/Euclidean_distance)).
- `cosineDistance`, also called cosine similarity, is the cosine of the angle between two (non-zero) vectors
([Wikipedia](https://en.wikipedia.org/wiki/Cosine_similarity)).
`L2Distance` is also called Euclidean distance, the Euclidean distance between two points in Euclidean space is the length of a line segment between the two points.
For example: If we have point P(p1,p2), Q(q1,q2), their distance will be d(p,q)
![L2Distance](https://en.wikipedia.org/wiki/Euclidean_distance#/media/File:Euclidean_distance_2d.svg)
For normalized data, `L2Distance` is usually a better choice, otherwise `cosineDistance` is recommended to compensate for scale. If no
distance function was specified during index creation, `L2Distance` is used as default.
`cosineDistance` also called cosine similarity is a measure of similarity between two non-zero vectors defined in an inner product space. Cosine similarity is the cosine of the angle between the vectors; that is, it is the dot product of the vectors divided by the product of their lengths.
![cosineDistance](https://www.tyrrell4innovation.ca/wp-content/uploads/2021/06/rsz_jenny_du_miword.png)
The Euclidean distance corresponds to the L2-norm of a difference between vectors. The cosine similarity is proportional to the dot product of two vectors and inversely proportional to the product of their magnitudes.
![compare](https://www.researchgate.net/publication/320914786/figure/fig2/AS:558221849841664@1510101868614/The-difference-between-Euclidean-distance-and-cosine-similarity.png)
In one sentence: cosine similarity care only about the angle between them, but do not care about the "distance" we normally think.

## One {#data-format-one}
Special input format that doesn't read any data from file and returns only one row with column of type `UInt8`, name `dummy` and value `0` (like `system.one` table).
Can be used with virtual columns `_file/_path` to list all files without reading actual data.
Example:
Query:
```sql
SELECT _file FROM file('path/to/files/data*', One);
```
Result:
```text
┌─_file────┐
│ data.csv │
└──────────┘
┌─_file──────┐

┌─_file────────┐
│ data.parquet │
└──────────────┘
```
## LineAsString {#lineasstring}
In this format, every line of input data is interpreted as a single string value. This format can only be parsed for table with a single field of type [String](/docs/en/sql-reference/data-types/string.md). The remaining columns must be set to [DEFAULT](/docs/en/sql-reference/statements/create/table.md/#default) or [MATERIALIZED](/docs/en/sql-reference/statements/create/table.md/#materialized), or omitted.

We recommend periodically updating the dictionaries with the geobase. During an update, generate new files and write them to a separate location. When everything is ready, rename them to the files used by the server.
There are also functions for working with OS identifiers and search engines, but they shouldn’t be used.
## Embedded Dictionaries
<SelfManaged />
ClickHouse contains a built-in feature for working with a geobase.
This allows you to:
- Use a region’s ID to get its name in the desired language.
- Use a region’s ID to get the ID of a city, area, federal district, country, or continent.
- Check whether a region is part of another region.
- Get a chain of parent regions.
All the functions support “translocality,” the ability to simultaneously use different perspectives on region ownership. For more information, see the section “Functions for working with web analytics dictionaries”.
The internal dictionaries are disabled in the default package.
To enable them, uncomment the parameters `path_to_regions_hierarchy_file` and `path_to_regions_names_files` in the server configuration file.
The geobase is loaded from text files.
Place the `regions_hierarchy*.txt` files into the `path_to_regions_hierarchy_file` directory. This configuration parameter must contain the path to the `regions_hierarchy.txt` file (the default regional hierarchy), and the other files (`regions_hierarchy_ua.txt`) must be located in the same directory.
Put the `regions_names_*.txt` files in the `path_to_regions_names_files` directory.
You can also create these files yourself. The file format is as follows:
`regions_hierarchy*.txt`: TabSeparated (no header), columns:
- region ID (`UInt32`)
- parent region ID (`UInt32`)
- region type (`UInt8`): 1 - continent, 3 - country, 4 - federal district, 5 - region, 6 - city; other types do not have values
- population (`UInt32`) — optional column
`regions_names_*.txt`: TabSeparated (no header), columns:
- region ID (`UInt32`)
- region name (`String`) — Can’t contain tabs or line feeds, even escaped ones.
A flat array is used for storing in RAM. For this reason, IDs shouldn’t be more than a million.
Dictionaries can be updated without restarting the server. However, the set of available dictionaries is not updated.
For updates, the file modification times are checked. If a file has changed, the dictionary is updated.
The interval to check for changes is configured in the `builtin_dictionaries_reload_interval` parameter.
Dictionary updates (other than loading at first use) do not block queries. During updates, queries use the old versions of dictionaries. If an error occurs during an update, the error is written to the server log, and queries continue using the old version of dictionaries.
We recommend periodically updating the dictionaries with the geobase. During an update, generate new files and write them to a separate location. When everything is ready, rename them to the files used by the server.
There are also functions for working with OS identifiers and search engines, but they shouldn’t be used.

This statement allows to move an access entity from one access storage to another.
Syntax:
```sql
MOVE {USER, ROLE, QUOTA, SETTINGS PROFILE, ROW POLICY} name1 [, name2, ...] TO access_storage_type

Currently, there are five access storages in ClickHouse:
- `local_directory`
- `memory`
- `replicated`
- `users_xml` (ro)
- `ldap` (ro)
Examples:
```sql
MOVE USER test TO local_directory
