clickhouse-cluster's Introduction

Clickhouse cluster on Docker

Конфигурация кластера: 2 шарда с двумя репликами в каждом шарде (см. include_from.xml) Каждая нода пишет свои данные в директорию ch*_volume

Запуск кластера

docker-compose up

Подключится к ноде ch1

clickhouse-client --host=127.0.0.1 --port=9011

Создать тестовую БД test_db на каждой ноде

create database test_db

На одной из нод создать реплицируемую таблицу (таблица создается на всех шардах и репликах)

CREATE TABLE IF NOT EXISTS test_db.events_shard ON CLUSTER test_cluster (
  event_date           Date DEFAULT toDate(now()),
  company_id           UInt32,
  product_id           UInt32
) ENGINE=ReplicatedMergeTree(
    '/clickhouse/tables/{shard}/events_shard', '{replica}',
    event_date,
    (company_id),
    8192
);

Создать Distributed таблицу для записи/чтения данных

CREATE TABLE IF NOT EXISTS test_db.events_dist
ON CLUSTER test_cluster AS test_db.events_shard
ENGINE = Distributed(test_cluster, test_db, events_shard, rand());

Запись в distributed таблицу

INSERT INTO test_db.events_dist (company_id, product_id) VALUES (1, 11), (1, 12), (1, 13);

Чтение из distributed таблицы

SELECT * FROM test_db.events_dist;
