## ClickHouse integration tests
|
||||
|
||||
This directory contains tests that involve several ClickHouse instances, custom configs, ZooKeeper, etc.
|
||||
|
||||
### Running
|
||||
|
||||
Prerequisites:
|
||||
* [docker](https://www.docker.com/community-edition#/download). Minimum required API version: 1.25, check with `docker version`.
|
||||
* [docker-compose](https://docs.docker.com/compose/). To install: `sudo pip install docker-compose`
|
||||
* [py.test](https://docs.pytest.org/) testing framework. To install: `sudo pip install pytest`
|
||||
|
||||
If you want to run the tests under a non-privileged user, you must add this user to `docker` group: `sudo usermod -aG docker $USER`.
|
||||
|
||||
Run the tests with the `pytest` command. To select which tests to run, use: `pytest -k <test_name_pattern>`
|
||||
|
||||
By default tests are run with system-wide client binary, server binary and base configs. To change that,
|
||||
set the following environment variables:
|
||||
* `CLICKHOUSE_TESTS_SERVER_BIN_PATH` to choose the server binary.
|
||||
* `CLICKHOUSE_TESTS_CLIENT_BIN_PATH` to choose the client binary.
|
||||
* `CLICKHOUSE_TESTS_BASE_CONFIG_DIR` to choose the directory from which base configs (`config.xml` and
|
||||
`users.xml`) are taken.
|
||||
|
||||
### Adding new tests
|
||||
|
||||
To add new test named `foo`, create a directory `test_foo` with an empty `__init__.py` and a file
|
||||
named `test.py` containing tests in it. All functions with names starting with `test` will become test cases.
|
||||
|
||||
`helpers` directory contains utilities for:
|
||||
* Launching a ClickHouse cluster with or without ZooKeeper in docker containers.
|
||||
* Sending queries to launched instances.
|
||||
* Introducing network failures such as severing network link between two instances.
|
||||
|
||||
To assert that two TSV files must be equal, wrap them in the `TSV` class and use the regular `assert`
|
||||
statement. Example: `assert TSV(result) == TSV(reference)`. In case the assertion fails, `pytest`
|
||||
will automagically detect the types of variables and only the small diff of two files is printed.

max_block_size
|
||||
--------------
|
||||
Данные в ClickHouse обрабатываются по блокам (наборам кусочков столбцов). Внутренние циклы обработки одного блока достаточно эффективны, но при этом существуют заметные издержки на каждый блок. ``max_block_size`` - это рекомендация, какого размера блоки (в количестве строк) загружать из таблицы. Размер блока должен быть не слишком маленьким, чтобы издержки на каждый блок оставались незаметными, и не слишком большим, чтобы запрос с LIMIT-ом, который завершается уже после первого блока, выполнялся быстро; чтобы не использовалось слишком много оперативки при вынимании большого количества столбцов в несколько потоков; чтобы оставалась хоть какая-нибудь кэш-локальность.
