The database for gaming analytics and telemetry

Access to live data is vital for real-time analytics. With ClickPipes, available exclusively in ClickHouse Cloud, we provide a turn-key integration engine that makes ingesting large volumes of data effortless. Select an incoming data source and format, tune your schema, and let your pipeline run - no complex configurations needed.

With ClickPipes’ built-in PostgreSQL CDC (Change Data Capture) connector, users can seamlessly replicate transactional and operational data, including player activity, in-game purchases, inventory changes, matchmaking data, and session logs, directly from PostgreSQL to ClickHouse Cloud. This enables real-time analytics without the need for external ETL tools, which are often costly, slow, and not optimized for PostgreSQL. PostgreSQL changes are continuously streamed into ClickHouse, ensuring insights remain up to date without manual data refreshes or batch processing delays.

Our extensive library of table engines supports ingesting data from a wide range of formats and sources. From Kafka topics to S3 buckets, OLTP databases, and more - we have you covered, no matter where your data lives.

ClickHouse eliminates the complexity of data ingestion while maintaining high performance. Unlike other OLAP databases that require batching inserts for efficiency, ClickHouse optimizes for both high-velocity streaming data and smaller real-time payloads. Asynchronous inserts automatically handle batching, allowing game developers and analytics teams to focus on insights rather than managing ingestion pipelines. Whether analyzing live game events, monitoring player engagement, or tracking ad performance, ClickHouse ensures immediate access to fresh, actionable data without ingestion bottlenecks.

Data transformations are common pillars in many gaming analytics workflows. With ClickHouse, Materialized Views make transformations seamless. Automatically triggered when new data is inserted into source tables, these SQL-based views are used to easily extract, aggregate, and modify data as it arrives - eliminating the need to build bespoke data transformation pipelines yourself. Chaining Materialized Views together offers modularized flexibility, too.

Queries on Materialized Views are exceptionally fast, as their results are automatically stored in new tables. This ensures that applications that rely on these queries are even more responsive, no matter how many petabytes of data are being analyzed. Unlike other database providers, at ClickHouse, we don't hide valuable accelerating features like these behind higher pricing tiers or additional charges.

The ClickHouse Query Cache is available for further enhanced responsiveness and reduced resource consumption, best suited for frequently used and expensive queries. Additional tuning through indexes and projections provides additional optimizations to ensure ultimate performance, every time.

ClickHouse delivers the most efficient JSON storage for analytical workloads, significantly outperforming other databases in both compression and query performance. Benchmarks show that ClickHouse requires six times less disk space than PostgreSQL and is 9,000 times faster at analytical queries, while also easily outpacing MongoDB and Elasticsearch.

Unlike traditional row-based databases that store JSON as large text blobs, ClickHouse natively organizes JSON paths as compressed columns, ensuring that only relevant data is accessed for queries. This enables highly efficient storage, minimized I/O overhead, and unmatched aggregation speed, making ClickHouse the ideal choice for large-scale, event-driven gaming analytics.

For game developers, flexibility is critical as new games, updates, and features continuously introduce new event types. ClickHouse’s native JSON support eliminates the need for rigid schemas, allowing developers to ingest and analyze evolving in-game event data without performance trade-offs. This makes it easy to adapt to new gameplay mechanics, telemetry events, and monetization strategies without costly schema modifications or preprocessing. By combining best-in-class compression with fully parallelized query execution, ClickHouse ensures real-time insights at scale, lowering the barrier for developers to send and analyze data effortlessly.

ClickHouse is relied on by gaming companies all over the world to unlock value from data as soon as it arrives, powering user-facing analytics and workflows.

Unlike traditional databases, ClickHouse supports a REST and gRPC interface, allowing web developers to build lightweight applications on ClickHouse without the need to integrate with complex binary protocols.

Leveraging the tools and frameworks you love with ClickHouse is easy through our extensive ecosystem of integrations. These include popular utilities for data ingestion and visualization, as well as language clients, SQL clients, and more.
