# Getting Started Guide for Building ClickHouse
The building of ClickHouse is supported on Linux, FreeBSD and macOS.
ClickHouse can be build on Linux, FreeBSD and macOS. If you use Windows, you can still build ClickHouse in a virtual machine running Linux, e.g. [VirtualBox](https://www.virtualbox.org/) with Ubuntu.
If you use Windows, you need to create a virtual machine with Ubuntu. To start working with a virtual machine please install VirtualBox. You can download Ubuntu from the website: https://www.ubuntu.com/#download. Please create a virtual machine from the downloaded image (you should reserve at least 4GB of RAM for it). To run a command-line terminal in Ubuntu, please locate a program containing the word “terminal” in its name (gnome-terminal, konsole etc.) or just press Ctrl+Alt+T.
ClickHouse cannot work or build on a 32-bit system. You should acquire access to a 64-bit system and you can continue reading.
ClickHouse requires a 64-bit system to compile and run, 32-bit systems do not work.
## Creating a Repository on GitHub {#creating-a-repository-on-github}
To start working with ClickHouse repository you will need a GitHub account.
To start developing for ClickHouse you will need a [GitHub](https://www.virtualbox.org/) account. Please also generate a SSH key locally (if you don't have one already) and upload the public key to GitHub as this is a prerequisite for contributing patches.
You probably already have one, but if you do not, please register at https://github.com. In case you do not have SSH keys, you should generate them and then upload them on GitHub. It is required for sending over your patches. It is also possible to use the same SSH keys that you use with any other SSH servers - probably you already have those.
Next, create a fork of the [ClickHouse repository](https://github.com/ClickHouse/ClickHouse/) in your personal account by clicking the "fork" button in the upper right corner.
Create a fork of ClickHouse repository. To do that please click on the “fork” button in the upper right corner at https://github.com/ClickHouse/ClickHouse. It will fork your own copy of ClickHouse/ClickHouse to your account.
To contribute, e.g. a fix for an issue or a feature, please commit your changes to a branch in your fork, then create a "pull request" with the changes to the main repository.
The development process consists of first committing the intended changes into your fork of ClickHouse and then creating a “pull request” for these changes to be accepted into the main repository (ClickHouse/ClickHouse).
For working with Git repositories, please install `git`. In Ubuntu run these commands in a terminal:
To work with Git repositories, please install `git`. To do that in Ubuntu you would run in the command line terminal:
```sh
sudo apt update

## Cloning a Repository to Your Development Machine {#cloning-a-repository-to-your-development-machine}
Next, you need to download the source files onto your working machine. This is called “to clone a repository” because it creates a local copy of the repository on your working machine.
First, download the source files to your working machine, i.e. clone the repository:
Run in your terminal:
```sh
git clone git@github.com:your_github_username/ClickHouse.git # replace placeholder with your GitHub user name
cd ClickHouse
```
git clone git@github.com:your_github_username/ClickHouse.git # replace placeholder with your GitHub user name
cd ClickHouse
This command creates a directory `ClickHouse/` containing the source code of ClickHouse. If you specify a custom checkout directory after the URL but it is important that this path does not contain whitespaces as it may lead to problems with the build later on.

:::note
Instructions below assume you are building on Linux. If you are cross-compiling or building on macOS, please also check for operating system and architecture specific guides, such as building [on macOS for macOS](build-osx.md), [on Linux for macOS](build-cross-osx.md), [on Linux for Linux/RISC-V](build-cross-riscv.md) and so on.

## Build System {#build-system}
ClickHouse uses CMake and Ninja for building.
CMake - a meta-build system that can generate Ninja files (build tasks).
Ninja - a smaller build system with a focus on the speed used to execute those cmake generated tasks.

Tables with Distributed engine do not store any data of their own, but allow distributed query processing on multiple servers.
Reading is automatically parallelized. During a read, the table indexes on remote servers are used, if there are any.

- `secure` - Whether to use a secure SSL/TLS connection. Usually also requires specifying the port (the default secure port is `9440`). The server should listen on `<tcp_port_secure>9440</tcp_port_secure>` and be configured with correct certificates.
- `compression` - Use data compression. Default value: `true`.
When specifying replicas, one of the available replicas will be selected for each of the shards when reading. You can configure the algorithm for load balancing (the preference for which replica to access) – see the [load_balancing](../../../operations/settings/settings.md#settings-load_balancing) setting.
If the connection with the server is not established, there will be an attempt to connect with a short timeout. If the connection failed, the next replica will be selected, and so on for all the replicas. If the connection attempt failed for all the replicas, the attempt will be repeated the same way, several times.
This works in favour of resiliency, but does not provide complete fault tolerance: a remote server might accept the connection, but might not work, or work poorly.

## Schema inference modes {#schema-inference-modes}
Schema inference from the set of data files can work in 2 different modes: `default` and `union`.
The mode is controlled by the setting `schema_inference_mode`.
### Default mode {#default-schema-inference-mode}
In default mode, ClickHouse assumes that all files have the same schema and tries to infer the schema by reading files one by one until it succeeds.
Example:
Let's say we have 3 files `data1.jsonl`, `data2.jsonl` and `data3.jsonl` with the next content:
`data1.jsonl`:
```json
{"field1" : 1, "field2" : null}
{"field1" : 2, "field2" : null}
{"field1" : 3, "field2" : null}
```
`data2.jsonl`:
```json
{"field1" : 4, "field2" : "Data4"}
{"field1" : 5, "field2" : "Data5"}
{"field1" : 6, "field2" : "Data5"}
```
`data3.jsonl`:
```json
{"field1" : 7, "field2" : "Data7", "field3" : [1, 2, 3]}
{"field1" : 8, "field2" : "Data8", "field3" : [4, 5, 6]}
{"field1" : 9, "field2" : "Data9", "field3" : [7, 8, 9]}
```
Let's try to use schema inference on these 3 files:
```sql
:) DESCRIBE file('data{1,2,3}.jsonl') SETTINGS schema_inference_mode='default'
```
Result:
```text
┌─name───┬─type─────────────┐
│ field1 │ Nullable(Int64) │
│ field2 │ Nullable(String) │
└────────┴──────────────────┘
```
As we can see, we don't have `field3` from file `data3.jsonl`.
It happens because ClickHouse first tried to infer schema from file `data1.jsonl`, failed because of only nulls for field `field2`,
and then tried to infer schema from `data2.jsonl` and succeeded, so data from file `data3.jsonl` wasn't read.
### Union mode {#default-schema-inference-mode}
In union mode, ClickHouse assumes that files can have different schemas, so it infer schemas of all files and then union them to the common schema.
Let's say we have 3 files `data1.jsonl`, `data2.jsonl` and `data3.jsonl` with the next content:
`data1.jsonl`:
```json
{"field1" : 1}
{"field1" : 2}
{"field1" : 3}
```
`data2.jsonl`:
```json
{"field2" : "Data4"}
{"field2" : "Data5"}
{"field2" : "Data5"}
```
`data3.jsonl`:
```json
{"field3" : [1, 2, 3]}
{"field3" : [4, 5, 6]}
{"field3" : [7, 8, 9]}
```
Let's try to use schema inference on these 3 files:
```sql
:) DESCRIBE file('data{1,2,3}.jsonl') SETTINGS schema_inference_mode='union'
```
Result:
```text
┌─name───┬─type───────────────────┐
│ field1 │ Nullable(Int64) │
│ field2 │ Nullable(String) │
│ field3 │ Array(Nullable(Int64)) │
└────────┴────────────────────────┘
```
As we can see, we have all fields from all files.
Note:
- As some of the files may not contain some columns from the resulting schema, union mode is supported only for formats that support reading subset of columns (like JSONEachRow, Parquet, TSVWithNames, etc) and won't work for other formats (like CSV, TSV, JSONCompactEachRow, etc).
- If ClickHouse cannot infer the schema from one of the files, the exception will be thrown.
- If you have a lot of files, reading schema from all of them can take a lot of time.

## substring(s, offset, length)
## substring
Returns a substring with `length` many bytes, starting at the byte at index `offset`. Character indexing starts from 1.
Returns the substring of a string `s` which starts at the specified byte index `offset`. Byte counting starts from 1. If `offset` is 0, an empty string is returned. If `offset` is negative, the substring starts `pos` characters from the end of the string, rather than from the beginning. An optional argument `length` specifies the maximum number of bytes the returned substring may have.
**Syntax**
```sql
substring(s, offset, length)
substring(s, offset[, length])
```
Alias:
- `substr`
- `mid`
**Arguments**
- `s` — The string to calculate a substring from. [String](../../sql-reference/data-types/string.md), [FixedString](../../sql-reference/data-types/fixedstring.md) or [Enum](../../sql-reference/data-types/enum.md)
- `offset` — The starting position of the substring in `s` . [(U)Int*](../../sql-reference/data-types/int-uint.md).
- `length` — The maximum length of the substring. [(U)Int*](../../sql-reference/data-types/int-uint.md). Optional.
**Returned value**
A substring of `s` with `length` many bytes, starting at index `offset`.

## Live View [Experimental]
## Live View [Deprecated]
:::note
This is an experimental feature that may change in backwards-incompatible ways in the future releases. Enable usage of live views and `WATCH` query using [allow_experimental_live_view](../../../operations/settings/settings.md#allow-experimental-live-view) setting. Input the command `set allow_experimental_live_view = 1`.
:::
This feature is deprecated and will be removed in the future.
```sql
CREATE LIVE VIEW [IF NOT EXISTS] [db.]table_name [WITH REFRESH [value_in_sec]] AS SELECT ...
```
Live views store result of the corresponding [SELECT](../../../sql-reference/statements/select/index.md) query and are updated any time the result of the query changes. Query result as well as partial result needed to combine with new data are stored in memory providing increased performance for repeated queries. Live views can provide push notifications when query result changes using the [WATCH](../../../sql-reference/statements/watch.md) query.
Live views are triggered by insert into the innermost table specified in the query.
Live views work similarly to how a query in a distributed table works. But instead of combining partial results from different servers they combine partial result from current data with partial result from the new data. When a live view query includes a subquery then the cached partial result is only stored for the innermost subquery.
:::info
- [Table function](../../../sql-reference/table-functions/index.md) is not supported as the innermost table.
- Tables that do not have inserts such as a [dictionary](../../../sql-reference/dictionaries/index.md), [system table](../../../operations/system-tables/index.md), a [normal view](#normal), or a [materialized view](#materialized) will not trigger a live view.
- Only queries where one can combine partial result from the old data plus partial result from the new data will work. Live view will not work for queries that require the complete data set to compute the final result or aggregations where the state of the aggregation must be preserved.
- Does not work with replicated or distributed tables where inserts are performed on different nodes.
- Can't be triggered by multiple tables.
See [WITH REFRESH](#live-view-with-refresh) to force periodic updates of a live view that in some cases can be used as a workaround.
:::
### Monitoring Live View Changes
You can monitor changes in the `LIVE VIEW` query result using [WATCH](../../../sql-reference/statements/watch.md) query.
```sql
WATCH [db.]live_view
```
**Example:**
```sql
CREATE TABLE mt (x Int8) Engine = MergeTree ORDER BY x;
CREATE LIVE VIEW lv AS SELECT sum(x) FROM mt;
```
Watch a live view while doing a parallel insert into the source table.
```sql
WATCH lv;
```
```bash
┌─sum(x)─┬─_version─┐
│ 1 │ 1 │
└────────┴──────────┘
┌─sum(x)─┬─_version─┐
│ 3 │ 2 │
└────────┴──────────┘
┌─sum(x)─┬─_version─┐
│ 6 │ 3 │
└────────┴──────────┘
```
```sql
INSERT INTO mt VALUES (1);
INSERT INTO mt VALUES (2);
INSERT INTO mt VALUES (3);
```
Or add [EVENTS](../../../sql-reference/statements/watch.md#events-clause) clause to just get change events.
```sql
WATCH [db.]live_view EVENTS;
```
**Example:**
```sql
WATCH lv EVENTS;
```
```bash
┌─version─┐
│ 1 │
└─────────┘
┌─version─┐
│ 2 │
└─────────┘
┌─version─┐
│ 3 │
└─────────┘
```
You can execute [SELECT](../../../sql-reference/statements/select/index.md) query on a live view in the same way as for any regular view or a table. If the query result is cached it will return the result immediately without running the stored query on the underlying tables.
```sql
SELECT * FROM [db.]live_view WHERE ...
```
### Force Live View Refresh
You can force live view refresh using the `ALTER LIVE VIEW [db.]table_name REFRESH` statement.
### WITH REFRESH Clause
When a live view is created with a `WITH REFRESH` clause then it will be automatically refreshed after the specified number of seconds elapse since the last refresh or trigger.
```sql
CREATE LIVE VIEW [db.]table_name WITH REFRESH [value_in_sec] AS SELECT ...
```
If the refresh value is not specified then the value specified by the [periodic_live_view_refresh](../../../operations/settings/settings.md#periodic-live-view-refresh) setting is used.
**Example:**
```sql
CREATE LIVE VIEW lv WITH REFRESH 5 AS SELECT now();
WATCH lv
```
```bash
┌───────────────now()─┬─_version─┐
│ 2021-02-21 08:47:05 │ 1 │
└─────────────────────┴──────────┘
┌───────────────now()─┬─_version─┐
│ 2021-02-21 08:47:10 │ 2 │
└─────────────────────┴──────────┘
┌───────────────now()─┬─_version─┐
│ 2021-02-21 08:47:15 │ 3 │
└─────────────────────┴──────────┘
```
```sql
WATCH lv
```
```
Code: 60. DB::Exception: Received from localhost:9000. DB::Exception: Table default.lv does not exist..
```
### Live View Usage
Most common uses of live view tables include:
- Providing push notifications for query result changes to avoid polling.
- Caching results of most frequent queries to provide immediate query results.
- Watching for table changes and triggering a follow-up select queries.
- Watching metrics from system tables using periodic refresh.
