Support Validate And Related Logic In Snapshot

by ADMIN 47 views

Problem Statement

Detecting conflicts in data storage systems is a crucial aspect of maintaining data integrity. To achieve this, it is essential to have a robust validation mechanism that scans manifests and validates against history. This feature request aims to add support for validate and related logic in the Snapshot module of Apache Iceberg.

Current Challenges

Currently, the detection of conflicts relies on manual checks and ad-hoc solutions, which can lead to errors and inconsistencies. The lack of a standardized validation mechanism makes it challenging to ensure data accuracy and reliability. To address this issue, we need to implement a comprehensive validation system that can scan manifests and validate against history.

Solution Overview

The proposed solution involves adding related logic to the SnapshotProduceOperation class, which will enable different actions like RowDelta, OverwriteFiles, and RewriteFiles to use and override (if needed) the validation mechanism. This will provide a flexible and extensible solution for conflict detection and validation.

Key Components

1. SnapshotProduceOperation

The SnapshotProduceOperation class will serve as the central hub for validation and related logic. It will provide a standardized interface for different actions to use and override the validation mechanism.

2. RowDelta

The RowDelta action will utilize the validation mechanism to detect conflicts between the current and previous snapshots. This will ensure that any changes made to the data are accurately reflected in the snapshot.

3. OverwriteFiles

The OverwriteFiles action will use the validation mechanism to verify that the files being overwritten are up-to-date and accurate. This will prevent any potential conflicts or data inconsistencies.

4. RewriteFiles

The RewriteFiles action will leverage the validation mechanism to ensure that the rewritten files are consistent with the previous snapshot. This will maintain data integrity and prevent any potential conflicts.

Implementation Details

The implementation will involve the following steps:

  1. Add validation logic to SnapshotProduceOperation: This will involve creating a standardized interface for validation and related logic.
  2. Implement RowDelta validation: This will involve utilizing the validation mechanism to detect conflicts between the current and previous snapshots.
  3. Implement OverwriteFiles validation: This will involve using the validation mechanism to verify that the files being overwritten are up-to-date and accurate.
  4. Implement RewriteFiles validation: This will involve leveraging the validation mechanism to ensure that the rewritten files are consistent with the previous snapshot.

Benefits and Advantages

The proposed solution will provide several benefits and advantages, including:

  • Improved data integrity: The validation mechanism will ensure that data is accurate and consistent across different snapshots.
  • Enhanced conflict detection: The solution will provide a comprehensive conflict detection mechanism, reducing the risk of data inconsistencies and errors.
  • Increased flexibility: The standardized interface for validation and related logic will enable different actions to use and override the validation mechanism, providing a flexible and extensible solution.
