Clever ingests 200x more logs at the same cost with ClickHouse Cloud

Clever, a leading K-12 education identity platform, transitioned from Datadog to ClickHouse Cloud to enhance its log indexing and analysis capabilities, handling 150 TB of data monthly from over 400 services and 200 AWS Lambdas. This switch allowed Clever to increase log indexing from 10% to 100% and extend log retention from 3 to 60 days without additional costs, achieving a 200x increase in searchable log volume. The infrastructure team developed a custom query layer that translates LogQL to SQL, providing engineers with a user-friendly log exploration experience. Clever's move to ClickHouse involved optimizing schema design for observability, using data skipping indexes, and ensuring multi-region resilience, which collectively improved query performance by 8-10 times. The transformation has enabled efficient log management, facilitating rapid debugging and trend analysis while maintaining cost-effectiveness and high availability across multiple AWS regions.
