"Amazon Ion is a richly-typed, self-describing, hierarchical data serialization format offering interchangeable binary and text representations. The text format (a superset of JSON) is easy to read and author, supporting rapid prototyping. The binary representation is efficient to store, transmit, and skip-scan parse. The rich type system provides unambiguous semantics for long-term preservation of data which can survive multiple generations of software evolution.
Ion was built to address rapid development, decoupling, and efficiency challenges faced every day while engineering large-scale, service-oriented architectures. It has been addressing these challenges within Amazon for nearly a decade, and we believe others will benefit as well.

(QLDB) "Documents – Documents exist within tables, and must be in Amazon Ion form. Ion is a superset of JSON that adds additional data types, type annotations, and comments. QLDB supports documents that contain nested JSON elements, and gives you the ability to write queries that reference and include these elements. Documents need not conform to any particular schema, giving you the flexibility to build applications that can easily adapt to changes."
