229-237: Document the storage configuration change in release notes.This change in default storage configuration for monitoring is significant enough to warrant:
- Clear documentation in release notes about the switch to file storage
- Migration guide for users currently using object storage
- Testing guidelines for validating monitoring data persistence
Would you like me to help draft the documentation or migration guide?

84-84: LGTM: Storage size aligns with new default value.The increase to 30Gi for monitoring storage matches the newly introduced
DefaultDataSizeForMonitoringconstant.

1-116: Verify object storage configuration removal.The AI summary indicates that object storage configuration should be removed from the monitoring section, but I notice the file still contains object storage configuration at the root level. Let's verify this is the intended behavior.
✅ Verification successful
Let me gather more specific information about the object storage configuration in these test files.
Based on the results, I can now provide a final response:
Object storage configuration is correctly placed at root level only
The verification shows that:
- Object storage is consistently configured at the root level of the GreptimeDBCluster spec in both test02 and test03
- There is no object storage configuration under the monitoring section in any of the test files
- A validation test comment explicitly states that "multiple objectStorage configs are not allowed"
The current configuration in the reviewed file is correct - object storage should only be present at the root level and not in the monitoring section.

The following scripts were executed for the analysis:

46-48: LGTM! The constant is well-defined and documented.The new constant follows the established naming and documentation patterns, and its value aligns with the PR's objective of refactoring storage configurations.
Let's verify how this constant is being used:
✅ Verification successful
Let me check the usage in
defaulting.goto ensure the constant is properly utilized.
Constant is properly integrated and used as intended
The verification shows that
DefaultDataSizeForMonitoringis:
- Defined in
constants.gowith proper documentation- Used correctly in
defaulting.gofor setting up file storage configuration for monitoring standalone- No other hardcoded "30Gi" values found that should be using this constant instead
The implementation aligns perfectly with the PR's objective of refactoring to use file storage for monitoring standalone by default.

The following scripts were executed for the analysis:

#!/bin/bash # Description: Verify the usage of DefaultDataSizeForMonitoring constant # Expected: Should be used in defaulting logic and monitoring configurations # Search for direct usage of the constant rg -l "DefaultDataSizeForMonitoring" # Search for the literal value "30Gi" to catch any places that might need to use the constant instead rg '"30Gi"' --type goLength of output: 181

229-237: Verify the impact of switching to file storage by default.The switch to file storage for monitoring standalone is a significant architectural change that could affect existing deployments. While the comment suggests this change is for "better performance and easy management", we should ensure:
- The default storage size (
DefaultDataSizeForMonitoring) is sufficient for typical monitoring workloads- Existing deployments using object storage have a migration path
Let's verify the constants being used:
✅ Verification successful
Let me gather more information about the object storage usage and configuration in the codebase to better understand the impact of this change.
This will help us understand:
- The current object storage configuration structure
- Where and how object storage is being used
- If there are any migration mechanisms in place
Based on the search results, I can now provide a final response as we have sufficient information about the object storage usage in the codebase.
The switch to file storage for monitoring is safe and well-justified
The change to use file storage by default for monitoring standalone is appropriate for the following reasons:
- The default size of 30Gi (defined as
DefaultDataSizeForMonitoring) is reasonable for monitoring workloads.- The change only affects the default behavior for new monitoring standalone deployments.
- Existing deployments are not impacted as:
- Object storage remains fully supported in the codebase (evidenced by extensive object storage provider code)
- Users can still explicitly configure object storage if needed
- The change only modifies the defaulting behavior, not the core functionality
The codebase shows robust support for various object storage providers (S3, GCS, OSS) with proper validation, configuration, and integration points, indicating this is just a change in default behavior rather than a removal of functionality.
