Summary

Redpanda has enhanced its cluster configuration system by using Raft and implementing a central API for configuration changes, which includes immediate validation to prevent operational issues in production systems. This improvement eliminates the need for traditional configuration files and reduces the risk of errors caused by invalid entries. The validation process now applies to all changes, whether made interactively or via scripted commands, ensuring that only verified configurations are stored. Redpanda Version 22.1 also introduces system sizing validation to manage resources efficiently during topic and partition creation, safeguarding against exceeding server capabilities. The use of C++20 and the Seastar framework enables robust live configuration changes without requiring full system restarts, allowing for atomic updates and active notifications of changes. Modern C++ features facilitate the translation of internal types to external metadata for the Admin API, and the Seastar model simplifies code while maintaining performance.
