Today’s blog focuses on Oracle 12c Release 2. With this release of the database additional new interesting functionality was introduced: sharding and analytics support for JSON. Very interesting in context of JSON processing – future blogs will continue the JSON SQL discussion.
Oracle as a JSON Database
With Oracle 12c Release 2’s functional additions Oracle 12c is providing all major functional areas of functionality in context of JSON processing. Non-functional areas (backup, restore, replication, HA/DR support, etc.) are supported as well, and there is no need to discuss those here.
The major areas of functionality in this context are
- JSON OLTP Processing. Oracle 12c supports general OLTP (online transaction processing) functionality. JSON documents are stored in tables and accessed through SQL (full DML support).
- JSON Analytics. Oracle 12c supports JSON analytics processing in the Oracle In-Memory option providing columnar representation and columnar processing.
- JSON Sharding. Oracle 12c supports managed sharding of data in tables of independently running databases (shards); up to 1000 shards currently.
Details of JSON OLTP, Analytics and Sharding
The following presentation contains a first level of details for the three areas above. I gave it during an Oracle Code event (https://go.oracle.com/oraclecode) in New York (https://developer.oracle.com/code/newyork) earlier this month. References to more detailed Oracle 12c documentation are provided in the presentation itself.
