Fluent Bit is a fast, lightweight, and highly scalable logging and metrics processor and forwarder that has solved the challenge of ingesting data from various sources into popular backends like ClickHouse. To set up Fluent Bit to route logs to ClickHouse in under 5 minutes, users need to create a database and tables in ClickHouse, configure Fluent Bit on Ubuntu, specify inputs, filters, and outputs, run Fluent Bit with the configuration file, and search the logs in ClickHouse. The setup allows for ad-hoc queries for analysis without designating any schema, enabling flexible data exploration.
