ClickHouse database patterns, query optimization, analytics, and data engineering best practices for high-performance analytical workloads.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# ClickHouse 分析パターン
高性能分析とデータエンジニアリングのためのClickHouse固有のパターン。
## 概要
ClickHouseは、オンライン分析処理（OLAP）用のカラム指向データベース管理システム（DBMS）です。大規模データセットに対する高速分析クエリに最適化されています。
**主な機能:**
- カラム指向ストレージ
- データ圧縮
- 並列クエリ実行
- 分散クエリ
- リアルタイム分析
## テーブル設計パターン
### MergeTreeエンジン（最も一般的）
```sql
CREATE TABLE markets_analytics (
date Date,
market_id String,
market_name String,
volume UInt64,
trades UInt32,
unique_traders UInt32,
avg_trade_size Float64,
created_at DateTime
) ENGINE = MergeTree()
PARTITION BY toYYYYMM(date)
ORDER BY (date, market_id)
SETTINGS index_granularity = 8192;
```
### ReplacingMergeTree（重複排除）
```sql
-- 重複がある可能性のあるデータ（複数のソースからなど）用
CREATE TABLE user_events (
event_id String,
user_id String,
event_type String,
timestamp DateTime,
properties String
) ENGINE = ReplacingMergeTree()
PARTITION BY toYYYYMM(timestamp)
ORDER BY (user_id, event_id, timestamp)
PRIMARY KEY (user_id, event_id);
```
### AggregatingMergeTree（事前集計）
```sql
-- 集計メトリクスの維持用
CREATE TABLE market_stats_hourly (
hour DateTime,
market_id String,
total_volume AggregateFunction(sum, UInt64),
total_trades AggregateFunction(count, UInt32),

How to install
mdr add affaan-m/ecc/clickhouse-io@sha256:4eb6b05f9b6a45c8The line at the top of this page pins the label git:20260704.ee2663d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
