Problem: Current Snapshot Restore Limitations in Kibana

Restoring a snapshot in Kibana can be a complex and time-consuming process, especially when dealing with large datasets and multiple indices. However, the current implementation of snapshot restore in Kibana can lead to unexpected failures, causing frustration and wasting valuable time. One of the common issues encountered during snapshot restore is the presence of open indices, which can prevent the restore process from completing successfully.

Error Messages and Manual Troubleshooting

When attempting to restore a snapshot in Kibana, users may encounter error messages such as:

cannot restore index because an open index with same name already exists

These error messages can be cryptic and do not provide sufficient information to troubleshoot the issue. As a result, users are forced to manually investigate the problem, which can be a time-consuming and labor-intensive process. This can lead to delays in restoring the snapshot, affecting the overall performance and reliability of the system.

Proposal: Add Dry-Run Option for Snapshot Restore

To address the limitations of the current snapshot restore implementation in Kibana, we propose the addition of a dry-run option to the snapshot restore UI. This feature would allow users to simulate the restore process and identify potential conflicts, such as open indices or shard mismatches, before execution.

Benefits of Dry-Run Option

The dry-run option would provide several benefits, including:

Prevents unexpected failures: By simulating the restore process, users can identify potential conflicts and take corrective action before attempting the actual restore.
Provides clear guidance before restore: The dry-run option would provide users with a clear understanding of the restore process and any potential issues that may arise.
Saves troubleshooting time: By identifying potential conflicts during the dry-run process, users can avoid the time-consuming process of manual troubleshooting.

Implementation Details

To implement the dry-run option, the following steps can be taken:

Add dry-run option to snapshot restore UI: A new option can be added to the snapshot restore UI, allowing users to select the dry-run option.
Simulate restore process: When the dry-run option is selected, the system would simulate the restore process, identifying potential conflicts such as open indices or shard mismatches.
Provide detailed error messages: The system would provide detailed error messages, including the specific conflicts that were encountered during the dry-run process.
Allow users to take corrective action: Users would be able to take corrective action, such as closing open indices or adjusting shard settings, before attempting the actual restore.

Conclusion

The addition of a dry-run option to the snapshot restore UI in Kibana would significantly improve the user experience and align with best practices for safer restores. By simulating the restore process and identifying potential conflicts, users can prevent unexpected failures, provide clear guidance before restore, and save troubleshooting time. We believe that this feature would be a valuable addition to Kibana and would greatly benefit users who rely on the platform for snapshot restore and management.

Future Development

In addition to the dry-run option, there are several other features that could be developed to improve the snapshot restore process in Kibana. Some potential features include:

Automated conflict resolution: The system could automatically resolve conflicts, such as closing open indices or adjusting shard settings, to prevent restore failures.
Customizable restore settings: Users could customize the restore settings, such as the number of shards or the indexing buffer size, to optimize the restore process for their specific use case.
Real-time monitoring and logging: The system could provide real-time monitoring and logging of the restore process, allowing users to track the progress and identify any issues that may arise.
