Simple tool for table data obfuscation.
|

A simple tool for table data obfuscation.

It allows to publish almost real production data for usage in benchmarks.

It reads an input table and produces an output table, that retains some properties of input, but contains different data.
|
||||
It allows publishing almost real production data for usage in benchmarks.
|
||||
|
||||
It is designed to retain the following properties of data:
|
||||
- cardinalities of values (number of distinct values) for every column and for every tuple of columns;
|
||||
- conditional cardinalities: number of distinct values of one column under condition on value of another column;
|
||||
- probability distributions of absolute value of integers; sign of signed integers; exponent and sign for floats;
|
||||
- probability distributions of length of strings;
|
||||
- probability of zero values of numbers; empty strings and arrays, NULLs;

- probability distributions of the absolute value of integers; the sign of signed integers; exponent and sign for floats;
|
||||
- probability distributions of the length of strings;
|
||||
- probability of zero values of numbers; empty strings and arrays, `NULL`s;
|
||||
|
||||
- data compression ratio when compressed with LZ77 and entropy family of codecs;
|
||||
- continuity (magnitude of difference) of time values across table; continuity of floating point values.
|
||||
- date component of DateTime values;
|
||||
- continuity (magnitude of difference) of time values across the table; continuity of floating-point values;
|
||||
- date component of `DateTime` values;
|
||||
|

- UTF-8 validity of string values;
|
||||
- string values continue to look somewhat natural.
|
||||
- string values look natural.
|

Most of the properties above are viable for performance testing:

reading data, filtering, aggregatio, and sorting will work at almost the same speed

It works in deterministic fashion: you define a seed value and transform is totally determined by input data and by seed.

Some transforms are one to one and could be reversed, so you need to have large enough seed and keep it in secret.

It uses some cryptographic primitives to transform data but from the cryptographic point of view, it doesn't do it properly, that is why you should not consider the result as secure unless you have another reason. The result may retain some data you don't want to publish.

It may retain some data you don't want to publish.
|
||||
|
||||
It always leave numbers 0, 1, -1 as is. Also it leaves dates, lengths of arrays and null flags exactly as in source data.
|
||||
For example, you have a column IsMobile in your table with values 0 and 1. In transformed data, it will have the same value.
|
||||
So, the user will be able to count exact ratio of mobile traffic.
|

It always leaves 0, 1, -1 numbers, dates, lengths of arrays, and null flags exactly as in source data.
|
||||
For example, you have a column `IsMobile` in your table with values 0 and 1. In transformed data, it will have the same value.
|
||||
|
||||
Another example, suppose you have some private data in your table, like user email and you don't want to publish any single email address.
|
||||
If your table is large enough and contain multiple different emails and there is no email that have very high frequency than all others,
|
||||
It will perfectly anonymize all data. But if you have small amount of different values in a column, it can possibly reproduce some of them.
|
||||
And you should take care and look at exact algorithm, how this tool works, and probably fine tune some of it command line parameters.
|
||||
So, the user will be able to count the exact ratio of mobile traffic.
|
||||
|
||||
This tool works fine only with reasonable amount of data (at least 1000s of rows).
|
||||
Let's give another example. When you have some private data in your table, like user email and you don't want to publish any single email address.
|
||||
If your table is large enough and contains multiple different emails and no email has a very high frequency than all others, it will anonymize all data. But if you have a small number of different values in a column, it can reproduce some of them.
|
||||
You should look at the working algorithm of this tool works, and fine-tune its command line parameters.
|
||||
|
||||
This tool works fine only with an average amount of data (at least 1000s of rows).

The `sum` function interprets `NULL` as `0`. In particular, this means that if the function receives input of a selection where all the values are `NULL`, then the result will be `0`, not `NULL`.

## initializeAggregation {#initializeaggregation}
|
||||
|
||||
Initializes aggregation for your input rows. It is intended for the functions with the suffix `State`.
|
||||
Use it for tests or to process columns of types `AggregateFunction` and `AggregationgMergeTree`.
|
||||
|
||||
**Syntax**
|
||||
|
||||
``` sql
|
||||
initializeAggregation (aggregate_function, column_1, column_2);
|
||||
```
|
||||
|
||||
**Parameters**
|
||||
|
||||
- `aggregate_function` — Name of the aggregation function. The state of this function — the creating one. [String](../../../sql-reference/data-types/string.md#string).
|
||||
- `column_n` — The column to translate it into the function as it's argument. [String](../../../sql-reference/data-types/string.md#string).
|
||||
|
||||
**Returned value(s)**
|
||||
|
||||
Returns the result of the aggregation for your input rows. The return type will be the same as the return type of function, that `initializeAgregation` takes as first argument.
|
||||
For example for functions with the suffix `State` the return type will be `AggregateFunction`.
|
||||
|
||||
**Example**
|
||||
|
||||
Query:
|
||||
|
||||
```sql
|
||||
SELECT uniqMerge(state) FROM (SELECT initializeAggregation('uniqState', number % 3) AS state FROM system.numbers LIMIT 10000);

||||
- All the expressions in the [SELECT](../../../sql-reference/statements/select/index.md), [HAVING](../../../sql-reference/statements/select/having.md), and [ORDER BY](../../../sql-reference/statements/select/order-by.md) clauses **must** be calculated based on key expressions **or** on [aggregate functions](../../../sql-reference/aggregate-functions/index.md) over non-key expressions (including plain columns). In other words, each column selected from the table must be used either in a key expression or inside an aggregate function, but not both.
|
||||
- Result of aggregating `SELECT` query will contain as many rows as there were unique values of “grouping key” in source table. Usually this signficantly reduces the row count, often by orders of magnitude, but not necessarily: row count stays the same if all “grouping key” values were distinct.

## WITH ROLLUP Modifier {#with-rollup-modifier}
|
||||
|
||||
`WITH ROLLUP` modifier is used to calculate subtotals for the key expressions, based on their order in the `GROUP BY` list. The subtotals rows are added after the result table.
|
||||
|
||||
The subtotals are calculated in the reverse order: at first subtotals are calculated for the last key expression in the list, then for the previous one, and so on up to the first key expression.
|
||||
|
||||
In the subtotals rows the values of already "grouped" key expressions are set to `0` or empty line.
|
||||
|
||||
!!! note "Note"
|
||||
Mind that [HAVING](../../../sql-reference/statements/select/having.md) clause can affect the subtotals results.
|
||||
|
||||
**Example**
|
||||
|
||||
Consider the table t:
|
||||
|
||||
```text
|
||||
┌─year─┬─month─┬─day─┐

|
||||
As `GROUP BY` section has three key expressions, the result contains four tables with subtotals "rolled up" from right to left:
|
||||
|
||||
- `GROUP BY year, month, day`;
|
||||
- `GROUP BY year, month` (and `day` column is filled with zeros);
|
||||
- `GROUP BY year` (now `month, day` columns are both filled with zeros);
|
||||
- and totals (and all three key expression columns are zeros).

|
||||
|
||||
`WITH CUBE` modifier is used to calculate subtotals for every combination of the key expressions in the `GROUP BY` list. The subtotals rows are added after the result table.
|
||||
|
||||
In the subtotals rows the values of all "grouped" key expressions are set to `0` or empty line.

||||
|
||||
As `GROUP BY` section has three key expressions, the result contains eight tables with subtotals for all key expression combinations:
|
||||
|
||||
- `GROUP BY year, month, day`
|
||||
- `GROUP BY year, month`
|
||||
- `GROUP BY year, day`
|

- `GROUP BY month, day`
|
||||
- `GROUP BY month`
|
||||
- `GROUP BY day`
|
||||
- and totals.

## WITH TOTALS Modifier {#with-totals-modifier}
|
||||
|

However, in contrast to standard SQL, if the table doesn’t have any rows (either there aren’t any at all, or there aren’t any after using WHERE to filter), an empty result is returned, and not the result from one of the rows containing the initial values of aggregate functions.
|
||||
|
||||
As opposed to MySQL (and conforming to standard SQL), you can’t get some value of some column that is not in a key or aggregate function (except constant expressions). To work around this, you can use the ‘any’ aggregate function (get the first encountered value) or ‘min/max’.

`GROUP BY` is not supported for array columns.

A constant can’t be specified as arguments for aggregate functions. Example: `sum(1)`. Instead of this, you can get rid of the constant. Example: `count()`.

Aggregation is one of the most important features of a column-oriented DBMS, and thus it’s implementation is one of the most heavily optimized parts of ClickHouse. By default, aggregation is done in memory using a hash-table. It has 40+ specializations that are chosen automatically depending on “grouping key” data types.

## SELECT modifiers {#select-modifiers}
|
||||
|
||||
You can use the following modifiers in `SELECT` queries.
|
||||
|
||||
### APPLY {#apply-modifier}
|
||||
|
||||
Allows you to invoke some function for each row returned by an outer table expression of a query.
|
||||
|
||||
**Syntax:**
|
||||
|
||||
``` sql
|
||||
SELECT <expr> APPLY( <func> ) FROM [db.]table_name
|
||||
```
|
||||
|
||||
**Example:**
|
||||
|
||||
``` sql
|
||||
CREATE TABLE columns_transformers (i Int64, j Int16, k Int64) ENGINE = MergeTree ORDER by (i);
|
||||
INSERT INTO columns_transformers VALUES (100, 10, 324), (120, 8, 23);
|
||||
SELECT * APPLY(sum) FROM columns_transformers;
|
||||
```
|
||||
|
||||
```
|
||||
┌─sum(i)─┬─sum(j)─┬─sum(k)─┐
|
||||
│ 220 │ 18 │ 347 │
|
||||
└────────┴────────┴────────┘
|
||||
```
|
||||
|
||||
### EXCEPT {#except-modifier}
|
||||
|
||||
Specifies the names of one or more columns to exclude from the result. All matching column names are omitted from the output.
|
||||
|
||||
**Syntax:**
|
||||
|
||||
``` sql
|
||||
SELECT <expr> EXCEPT ( col_name1 [, col_name2, col_name3, ...] ) FROM [db.]table_name
|
||||
```
|
||||
|
||||
**Example:**
|
||||
|
||||
``` sql
|
||||
SELECT * EXCEPT (i) from columns_transformers;
|
||||
```
|
||||
|
||||
```
|
||||
┌──j─┬───k─┐
|
||||
│ 10 │ 324 │
|
||||
│ 8 │ 23 │
|
||||
└────┴─────┘
|
||||
```
|
||||
|
||||
### REPLACE {#replace-modifier}
|
||||
|
||||
Specifies one or more [expression aliases](../../../sql-reference/syntax.md#syntax-expression_aliases). Each alias must match a column name from the `SELECT *` statement. In the output column list, the column that matches the alias is replaced by the expression in that `REPLACE`.
|
||||
|
||||
This modifier does not change the names or order of columns. However, it can change the value and the value type.
|
||||
|
||||
**Syntax:**
|
||||
|
||||
``` sql
|
||||
SELECT <expr> REPLACE( <expr> AS col_name) from [db.]table_name
|
||||
```
|
||||
|
||||
**Example:**
|
||||
|
||||
``` sql
|
||||
SELECT * REPLACE(i + 1 AS i) from columns_transformers;
|
||||
```
|
||||
|
||||
```
|
||||
┌───i─┬──j─┬───k─┐
|
||||
│ 101 │ 10 │ 324 │
|
||||
│ 121 │ 8 │ 23 │
|
||||
└─────┴────┴─────┘
|
||||
```
|
||||
|
||||
### Modifier Combinations {#modifier-combinations}
|
||||
|
||||
You can use each modifier separately or combine them.
|
||||
|
||||
**Examples:**
|
||||
|
||||
Using the same modifier multiple times.
|
||||
|
||||
``` sql
|
||||
SELECT COLUMNS('[jk]') APPLY(toString) APPLY(length) APPLY(max) from columns_transformers;
|
||||
```
|
||||
|
||||
```
|
||||
┌─max(length(toString(j)))─┬─max(length(toString(k)))─┐
|
||||
│ 2 │ 3 │
|
||||
└──────────────────────────┴──────────────────────────┘
|
||||
```
|
||||
|
||||
Using multiple modifiers in a single query.
|
||||
|
||||
``` sql
|
||||
SELECT * REPLACE(i + 1 AS i) EXCEPT (j) APPLY(sum) from columns_transformers;
|
||||
```
|
||||
|
||||
```
|
||||
┌─sum(plus(i, 1))─┬─sum(k)─┐
|
||||
│ 222 │ 347 │
|
||||
└─────────────────┴────────┘

# Обфускатор ClickHouse
|
||||
|
||||
Простой инструмент для обфускации табличных данных.
|
||||
|
||||
Он считывает данные входной таблицы и создает выходную таблицу, которая сохраняет некоторые свойства входных данных, но при этом содержит другие данные.
|
||||
|
||||
Это позволяет публиковать практически реальные данные и использовать их в тестах на производительность.
|
||||
|
||||
Обфускатор предназначен для сохранения следующих свойств данных:
|
||||
- кардинальность (количество уникальных данных) для каждого столбца и каждого кортежа столбцов;
|
||||
- условная кардинальность: количество уникальных данных одного столбца в соответствии со значением другого столбца;
|
||||
- вероятностные распределения абсолютного значения целых чисел; знак числа типа Int; показатель степени и знак для чисел с плавающей запятой;
|
||||
- вероятностное распределение длины строк;
|
||||
- вероятность нулевых значений чисел; пустые строки и массивы, `NULL`;
|
||||
- степень сжатия данных алгоритмом LZ77 и семейством энтропийных кодеков;
|
||||
|
||||
- непрерывность (величина разницы) значений времени в таблице; непрерывность значений с плавающей запятой;
|
||||
- дату из значений `DateTime`;
|
||||
|
||||
- кодировка UTF-8 значений строки;
|
||||
- строковые значения выглядят естественным образом.
|
||||
|
||||
|
||||
Большинство перечисленных выше свойств пригодны для тестирования производительности. Чтение данных, фильтрация, агрегирование и сортировка будут работать почти с той же скоростью, что и исходные данные, благодаря сохраненной кардинальности, величине, степени сжатия и т. д.
|
||||
|
||||
Он работает детерминированно. Вы задаёте значение инициализатора, а преобразование полностью определяется входными данными и инициализатором.
|
||||
|
||||
Некоторые преобразования выполняются один к одному, и их можно отменить. Поэтому нужно использовать большое значение инициализатора и хранить его в секрете.
|
||||
|
||||
|
||||
Обфускатор использует некоторые криптографические примитивы для преобразования данных, но, с криптографической точки зрения, результат будет небезопасным. В нем могут сохраниться данные, которые не следует публиковать.
|
||||
|
||||
|
||||
Он всегда оставляет без изменений числа 0, 1, -1, даты, длины массивов и нулевые флаги.
|
||||
Например, если у вас есть столбец `IsMobile` в таблице со значениями 0 и 1, то в преобразованных данных он будет иметь то же значение.
|
||||
|
||||
Таким образом, пользователь сможет посчитать точное соотношение мобильного трафика.
|
||||
|
||||
Давайте рассмотрим случай, когда у вас есть какие-то личные данные в таблице (например, электронная почта пользователя), и вы не хотите их публиковать.
|
||||
Если ваша таблица достаточно большая и содержит несколько разных электронных почтовых адресов, и ни один из них не встречается часто, то обфускатор полностью анонимизирует все данные. Но, если у вас есть небольшое количество разных значений в столбце, он может скопировать некоторые из них.
|
||||
В этом случае вам следует посмотреть на алгоритм работы инструмента и настроить параметры командной строки.
|
||||
|
||||
Обфускатор полезен в работе со средним объемом данных (не менее 1000 строк).

## initializeAggregation {#initializeaggregation}
|
||||
|
||||
Инициализирует агрегацию для введеных строчек. Предназначена для функций с суффиксом `State`.
|
||||
Поможет вам проводить тесты или работать со столбцами типов: `AggregateFunction` и `AggregationgMergeTree`.
|
||||
|
||||
**Синтаксис**
|
||||
|
||||
``` sql
|
||||
initializeAggregation (aggregate_function, column_1, column_2);
|
||||
```
|
||||
|
||||
**Параметры**
|
||||
|
||||
- `aggregate_function` — название функции агрегации, состояние которой нужно создать. [String](../../../sql-reference/data-types/string.md#string).
|
||||
- `column_n` — столбец, который передается в функцию агрегации как аргумент. [String](../../../sql-reference/data-types/string.md#string).
|
||||
|
||||
**Возвращаемое значение**
|
||||
|
||||
Возвращает результат агрегации введенной информации. Тип возвращаемого значения такой же, как и для функции, которая становится первым аргументом для `initializeAgregation`.
|
||||
|
||||
Пример:
|
||||
|
||||
Возвращаемый тип функций с суффиксом `State` — `AggregateFunction`.

|
||||
## Модификатор WITH ROLLUP {#with-rollup-modifier}
|
||||
|
||||
Модификатор `WITH ROLLUP` применяется для подсчета подытогов для ключевых выражений. При этом учитывается порядок следования ключевых выражений в списке `GROUP BY`. Подытоги подсчитываются в обратном порядке: сначала для последнего ключевого выражения в списке, потом для предпоследнего и так далее вплоть до самого первого ключевого выражения.
|
||||
|
||||
Строки с подытогами добавляются в конец результирующей таблицы. В колонках, по которым строки уже сгруппированы, указывается значение `0` или пустая строка.

Если в запросе есть секция [HAVING](../../../sql-reference/statements/select/having.md), она может повлиять на результаты расчета подытогов.
|
||||
|
||||
**Пример**
|
||||
|
||||
Рассмотрим таблицу t:
|
||||
|
||||
```text
|
||||
┌─year─┬─month─┬─day─┐
|
||||
│ 2019 │ 1 │ 5 │
|
||||
│ 2019 │ 1 │ 15 │
|
||||
│ 2020 │ 1 │ 5 │
|
||||
│ 2020 │ 1 │ 15 │
|
||||
│ 2020 │ 10 │ 5 │
|
||||
│ 2020 │ 10 │ 15 │
|
||||
└──────┴───────┴─────┘
|
||||
```
|
||||
|
||||
Запрос:
|
||||
|
||||
```sql
|
||||
SELECT year, month, day, count(*) FROM t GROUP BY year, month, day WITH ROLLUP;
|
||||
```
|
||||
|
||||
Поскольку секция `GROUP BY` содержит три ключевых выражения, результат состоит из четырех таблиц с подытогами, которые как бы "сворачиваются" справа налево:
|
||||
|
||||
- `GROUP BY year, month, day`;
|
||||
- `GROUP BY year, month` (а колонка `day` заполнена нулями);
|
||||
- `GROUP BY year` (теперь обе колонки `month, day` заполнены нулями);
|
||||
- и общий итог (все три колонки с ключевыми выражениями заполнены нулями).

## Модификатор WITH CUBE {#with-cube-modifier}
|
||||
|
||||
Модификатор `WITH CUBE` применятеся для расчета подытогов по всем комбинациям группировки ключевых выражений в списке `GROUP BY`.
|
||||
|
||||
Строки с подытогами добавляются в конец результирующей таблицы. В колонках, по которым выполняется группировка, указывается значение `0` или пустая строка.

||||

||||
```sql
|

SELECT year, month, day, count(*) FROM t GROUP BY year, month, day WITH CUBE;
|
||||
```
|
||||
|
||||
Поскольку секция `GROUP BY` содержит три ключевых выражения, результат состоит из восьми таблиц с подытогами — по таблице для каждой комбинации ключевых выражений:
|
||||
|
||||
- `GROUP BY year, month, day`
|
||||
- `GROUP BY year, month`
|
||||
- `GROUP BY year, day`
|
||||
- `GROUP BY year`
|
||||
- `GROUP BY month, day`
|
||||
- `GROUP BY month`
|
||||
- `GROUP BY day`
|
||||
- и общий итог.
|
||||
|
||||
Колонки, которые не участвуют в `GROUP BY`, заполнены нулями.

## Модификатор WITH TOTALS {#with-totals-modifier}
|
||||
|

Если указан модификатор `WITH TOTALS`, то будет посчитана ещё одна строчка, в которой в столбцах-ключах будут содержаться значения по умолчанию (нули, пустые строки), а в столбцах агрегатных функций - значения, посчитанные по всем строкам («тотальные» значения).

```

Но, в отличие от стандартного SQL, если в таблице нет строк (вообще нет или после фильтрации с помощью WHERE), в качестве результата возвращается пустой результат, а не результат из одной строки, содержащий «начальные» значения агрегатных функций.
|
||||
|
||||
В отличие от MySQL (и в соответствии со стандартом SQL), вы не можете получить какое-нибудь значение некоторого столбца, не входящего в ключ или агрегатную функцию (за исключением константных выражений). Для обхода этого вы можете воспользоваться агрегатной функцией any (получить первое попавшееся значение) или min/max.

GROUP BY вычисляет для каждого встретившегося различного значения ключей, набор значений агрегатных функций.

|
||||
Не поддерживается GROUP BY по столбцам-массивам.
|
||||

|

|
||||
Агрегация является одной из наиболее важных возможностей столбцовых СУБД, и поэтому её реализация является одной из наиболее сильно оптимизированных частей ClickHouse. По умолчанию агрегирование выполняется в памяти с помощью хэш-таблицы. Она имеет более 40 специализаций, которые выбираются автоматически в зависимости от типов данных ключа группировки.

<!-- Development Roadmap:
|
||||
|
||||
1. Add indication that the query was sent and when the query has been finished.
|
||||
Do not use any animated spinners. Just a text or check mark.
|
||||
Eliminate race conditions (results from the previous query should be ignored on arrival, the previous request should be cancelled).
|
||||
|
||||
2. Support readonly servers.
|
||||
1. Support readonly servers.
|
||||
Check if readonly = 1 (with SELECT FROM system.settings) to avoid sending settings. It can be done once on address/credentials change.
|
||||
It can be done in background, e.g. wait 100 ms after address/credentials change and do the check.
|
||||
Also it can provide visual indication that credentials are correct.
|
||||
|
||||
3. Add history in localstorage. Integrate with history API.
|
||||
There can be a counter in localstorage, that will be appended to location #fragment.
|
||||
The 'back', 'forward' buttons in browser should work.
|
||||
Also there should be UI element to list all the queries from history and select from the list.
|
||||
|
||||
4. Trivial sharing capabilities.
|
||||
Sharing is only possible when system.query_log is accessible. Read the X-ClickHouse-QueryId from the response.
|
||||
Share button will: - emit SYSTEM FLUSH LOGS if not readonly; - find the query in the query_log;
|
||||
- generate an URL with the query id and: server address if not equal to the URL's host; user name if not default;
|
||||
indication that password should be entered in case of non-empty password.
