We are pleased to welcome NANO Corp., a young French startup founded in 2019 by former defense personnel, as they share their journey from discovering ClickHouse to implementing it in production. NANO Corp.'s main goal is to analyze complex and changing network traffic at line-rate high speed using asynchronous feeds. They initially faced challenges with traditional RDBMS, including data schemes that relied on update speed and required clustering for performance issues. The company's pre-requisites were harsh, requiring top-notch performances over cost considerations. After exploring various options, they discovered ClickHouse, which met their needs due to its fast multiple inserts, indexing, materialized views, MergeTree function, and great documentation. Data ingestion in ClickHouse is more efficient, with a simpler architecture and less resource taxation, making it suitable for NANO Corp.'s technology, which involves sending data constantly while running constant queries on hot and cold data. The company stayed with ClickHouse despite other alternatives due to its perfect fit, overcoming their initial frustration with other databases.
