NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar. Understand more

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 is an open-source, columnar online analytical processing (OLAP) database for real-time analytics. It started as an experimental project in 2009 and has since matured into a highly performant and linearly scalable analytical database. Its efficient query processing engine together with data compression makes it suitable to run interactive queries without pre-aggregation. ClickHouse is also a great storage choice for OpenTelemetry data. Its integration with Jaeger allows you to store massive volumes of traces and analyze them efficiently.
