Fully managed ZooKeeper service
ClickHouse in Yandex.Cloud integrates on its own with a dedicated installation of the Apache Zookeeper service, which provides replication functions in this DBMS. Most actions for ZooKeeper management will run automatically.
Choice of storage type
It is easy to choose the data storage type for each cluster individually. We provide two options: network and local storage. The first option is more reliable and flexible, while the second one provides faster speeds.
Easy to maintain
Yandex.Cloud takes care of maintaining the databases and updating the DBMS to the latest versions. At the same time, you can easily configure the databases, restore them from backups, view logs, and use charts to monitor key performance indicators.
Replicas in different availability zones
If necessary, you can create cluster hosts in different availability zones. Data replication between ClickHouse hosts is performed automatically and asynchronously. Even with multiple replicas, the system remains transparent and easy to use: you can write and read data from any host in the cluster.
Encryption and isolation
In Yandex Managed Service for ClickHouse all DBMS connections and backups of the database contents are encrypted. Connections are secured via TLS. Public-key encryption is used for backups. Moreover, the databases of different Yandex.Cloud customers are completely isolated from each other. The databases do not use any shared components, so no one else can access the data you have uploaded.
Fast data processing
Yandex Managed Service for ClickHouse uses fast NVMe-enabled solid-state drives. The result is that you can expect high performance even when handling large amounts of data.
Use cases
You can track incidents in your service via instant requests and immediately see changes in metrics like error rate, user response time, and others. Just set up a regular upload of large data packages to ClickHouse. We recommend that you send more than a thousand rows at a time.
ClickHouse provides a convenient way to aggregate information that you collect through various systems, including distributed ones. Your experts will be able to quickly visualize data, customize dashboards to meet their needs, and analyze service events and business processes in real time.
