Oracle 23c is planned to end beta and go into GA sometime around February 2023, so it would be a cool new feature to add to Debezium 2.2 in Q1 2023.

Some highlights for Oracle 23c include:

1. SELECT without FROM, i.e. SELECT 2*3; (DBZ-7505)
2. Using column aliases in GROUP BY and HAVING clauses (checked against current grammar and aliases get treated as expressions, which is sufficient for our purposes).
3. Existence testing in DDL, i.e. CREATE TABLE tab IF NOT EXIST ... (DBZ-7498)
4. Table Value Constructors
5. New RETURNING keyword to get old/new values
6. New error messages to explain SQL failures better
7. Database object annotations - CREATE/ALTER TABLE (DBZ-7506)
8. New developer role
9. Javascript-based store procedure support
10. New SQL domain types support
11. Ability to issue updates against a table with a join condition
12. Schema-level permissions
13. JSON schema validation support
14. Define 4096 columns per table, like woah???
15. New BOOLEAN data type
16. Oracle RAC support on K8s
