ClickHouse is an open-source, distributed columnar online analytical processing (OLAP) database for real-time analytics. It has matured into a highly performant and scalable engine capable of handling large-scale data analytics. Its incremental materialized view, efficient query engine and strong data compression make it ideal for interactive queries. Built-in support for approximate aggregate functions enables trade-offs between accuracy and performance, which is especially useful for high-cardinality analytics. The addition of the S3 storage engine and MergeTree allows separation of storage and compute, using S3-compatible storage for ClickHouse tables. We’ve also found ClickHouse to be an excellent backend for OpenTelemetry data and crash analytics tools like Sentry. For teams seeking a fast, open-source analytics engine, ClickHouse is an excellent choice.
ClickHouse 是一个开源的列式在线分析处理（OLAP）数据库，用于实时分析。它于 2009 年作为一个实验项目启动，之后发展成为一个高性能且线性可扩展的分析数据库。其高效的查询处理引擎结合数据压缩，使其适合在不进行预聚合的情况下运行交互式查询。ClickHouse 也是 OpenTelemetry 数据的优秀存储选择。它与 Jaeger 的集成允许您存储大量的追踪数据并高效分析。
