Integrates audit functionality into CQL statement processing to enable tracking of database operations. Key changes:
- Add audit_info and statement_category to all CQL statements
- Implement audit categories for different statement types:
- DDL: Schema altering statements (CREATE/ALTER/DROP)
- DML: Data manipulation (INSERT/UPDATE/DELETE/TRUNCATE/USE)
- DCL: Access control (GRANT/REVOKE/CREATE ROLE)
- QUERY: SELECT statements
- ADMIN: Service level operations
- Add audit inspection points in query processing:
- Before statement execution
- After access checks
- After statement completion
- On execution failures
- Add password sanitization for role management statements
- Mask plaintext passwords in audit logs
- Handle both direct password parameters and options maps
- Preserve query structure while hiding sensitive data
- Modify prepared statement lifecycle to carry audit context
- Pass audit info during statement preparation
- Track audit info through statement execution
- Support batch statement auditing
This change enables comprehensive auditing of CQL operations while ensuring sensitive data is properly masked in audit logs.
