The Java API for JSON type in Oracle JDBC 20c
Oracle 20c (currently available as a preview release only) introduces a new built-in SQL type ('JSON') to support the efficient and type-rich storage of JSON data. Values are both stored and transmitted across the network using Oracle's binary JSON format to provide fast ingest, retrieval, query, and update of JSON data. This session will give an overview of the new JSON facilities in JDBC (package oracle.sql.json). Software engineer Josh Spiegel will cover functionality, architecture, and performance best practices for accessing JSON from a Java program. A mixture of slides and live demonstration will be used throughout the talk.
