Developers can now store JSON-based semi-structured data in Aurora DSQL using the JSONB data type, compatible with PostgreSQL tools and code. This capability enhances flexibility in combining relational and document data within the same database.

PostgreSQL compression is enabled by default for JSONB columns, reducing storage footprint of large JSON documents and potentially lowering costs. This feature is available in supported AWS Regions and helps users manage diverse data types natively.
