Same Job, Two Engines: InnoDB and Iceberg Internals

The article discusses the internal workings of InnoDB and Iceberg, two engines used in database systems. InnoDB is a widely used, open-source storage engine for MySQL, while Iceberg is a columnar storage engine developed by Apache. Both engines are designed to store and manage large amounts of data, but they differ in their approaches. InnoDB uses a row-based storage format, whereas Iceberg uses a column-based format. The article delves into the details of how each engine handles transactions, concurrency, and data compression. It also highlights the advantages and disadvantages of each engine, including their performance, scalability, and complexity. The author concludes that while InnoDB is a well-established and widely used engine, Iceberg offers a more modern and efficient approach to data storage, making it a promising alternative for large-scale data management.
