Refactor archival strategies in FILE_ARCHIVER package
- Removed CURRENT_MONTH_ONLY strategy, replacing it with MINIMUM_AGE_MONTHS = 0 for current month retention. - Updated validation logic to allow MINIMUM_AGE_MONTHS to be non-negative. - Consolidated documentation to reflect changes in archival strategies. - Adjusted rollback script to reset all archival parameters to NULL for 25 Release 01 tables. - Enhanced README and installation scripts to clarify new configuration requirements and usage examples. - Updated version history to indicate breaking changes and migration steps for existing configurations.

1. **Use CURRENT_MONTH_ONLY when**:

- Data is updated frequently (daily/intraday)
|
||||
1. **Use MINIMUM_AGE_MONTHS when**:
|
||||
- **MINIMUM_AGE_MONTHS = 0**: Current month only retention
|
||||
- Data updated frequently (daily/intraday)
|
||||
- Historical data access is rare
|
||||
- ODS bucket space is limited
|
||||
- Example: LM dissemination feeds
|
||||
|
||||
2. **Use MINIMUM_AGE_MONTHS when**:
|
||||
- **MINIMUM_AGE_MONTHS = N (N > 0)**: Multi-month retention
|
||||
- Regulatory compliance requires specific retention period
|
||||
- Analytical workloads need multi-month access
|
||||
- Analytical workloads need N-month access
|
||||
- Data updates are infrequent
|
||||
- Example: CSDB securities data (6-month retention)
|

- Complex retention requirements
|

- Combining current month access with minimum age threshold

- Combining month boundary check with minimum age threshold

- Advanced scenarios not covered by other strategies
