nastra opened a new pull request #3688: URL: https://github.com/apache/iceberg/pull/3688
## Motivation * Use true immutable objects that are type-safe, thread-safe, null-safe * Get builder classes for free * Get JSON serialization/deserialization for free (this will also be helpful for the REST-based Catalog #3424) This is relying on https://immutables.github.io/ (Apache License 2.0), which allows generating immutable objects and builders via annotation processing. * Immutable objects are serialization ready (including JSON and its binary forms) * Supports lazy, derived and optional attributes * Immutable objects are constructed once, in a consistent state, and can be safely shared * Will fail if mandatory attributes are missing * Cannot be sneakily modified when passed to other code * Immutable objects are naturally thread-safe and can therefore be safely shared among threads * No excessive copying * No excessive synchronization * Object definitions are pleasant to write and read * No boilerplate setter and getters * No ugly IDE-generated hashCode, equals and toString methods that end up being stored in source control. -- This is an automated message from the Apache Git Service.
