Enhancing OpenFGA Support For Ignoring Duplicates On Tuple Writes

Introduction

Hey guys! Today, we're diving deep into a critical feature request for OpenFGA that could significantly improve the efficiency of large-scale tuple imports and reconciliation processes. We're talking about the ability to ignore duplicates when writing tuples. If you're dealing with massive amounts of authorization data, this is something you'll definitely want to hear about. This article explores the challenges of importing large datasets into OpenFGA, the proposed solution to ignore duplicate tuples during writes, and the benefits this feature could bring to various use cases. Whether you're managing authorization for a growing application or synchronizing data across systems, understanding this enhancement can help you optimize your OpenFGA implementation. Let's get started and explore how we can make OpenFGA even more robust and user-friendly for large-scale deployments.

The Problem: Large-Scale Tuple Imports and Duplicates

When using OpenFGA for authorization, one common challenge arises when importing a large number of tuples. We're talking hundreds of millions, maybe even close to a billion tuples! Imagine setting up a new authorization system or migrating existing data – the sheer volume can be daunting. The current process involves bulk importing these tuples, but here's where the snag hits: if the import process fails midway and needs to be retried, some tuples might already exist in the database. This means that the system needs to check for duplicates, which can significantly slow down the import operation. Checking each tuple using the read API to avoid duplicates is a time-consuming process that adds a lot of overhead. This can be a major bottleneck, especially when you're under pressure to get things up and running quickly. We need a more efficient way to handle these situations, and that's where the idea of ignoring duplicates comes into play. This challenge highlights the need for a mechanism that allows OpenFGA to handle large datasets more gracefully, ensuring that retries and synchronization processes don't get bogged down by duplicate checks. By addressing this issue, we can make OpenFGA a more practical and scalable solution for organizations with extensive authorization needs.

The Ideal Solution: Ignoring Errors on Duplicate Tuples

The proposed solution is to introduce an API parameter that allows OpenFGA to ignore errors if any tuples from a batch already exist. This is similar to the ON CONFLICT (...) DO NOTHING clause in PostgreSQL, which is a highly efficient way to handle duplicate entries in a database. By implementing this feature, OpenFGA can bypass the time-consuming process of checking for existing tuples before writing them. Instead, the system can simply attempt to write the tuples and ignore any errors that arise due to duplicates. This approach offers several benefits. First, it significantly speeds up the import process, as there's no need to query the database for each tuple. Second, it simplifies the retry mechanism. If an import fails, you can simply retry the batch without worrying about whether some tuples have already been written. The system will automatically handle the duplicates. This feature also opens up possibilities for reconciliation processes. Imagine a scenario where you have a system that is the "source of truth" for authorization data, and you need to sync it with OpenFGA. With the ability to ignore duplicates, you can simply push all the tuples from the source of truth to OpenFGA, knowing that any existing tuples will be ignored. This makes the synchronization process much more straightforward and reliable. This enhancement would make OpenFGA more robust and easier to manage, particularly in large-scale deployments.

Use Cases and Benefits of Ignoring Duplicates

There are several scenarios where the ability to ignore duplicate tuples would be incredibly beneficial. One of the most significant is during the initial import of a large dataset. Imagine a company migrating its authorization data to OpenFGA. They might have hundreds of millions of tuples to import. Without the ability to ignore duplicates, the import process could take a very long time, as the system would need to check for duplicates for each tuple. With this feature, the import can be completed much faster, making the migration process smoother and more efficient. Another crucial use case is reconciliation. Many organizations have a system that acts as the source of truth for authorization data. This system might be a custom-built solution or a third-party identity provider. To keep OpenFGA in sync with this source of truth, a process needs to regularly push updates to OpenFGA. The ability to ignore duplicates simplifies this process significantly. The synchronization process can simply push all tuples from the source of truth to OpenFGA, and the system will automatically handle any duplicates. This ensures that OpenFGA remains consistent with the source of truth without the need for complex duplicate-checking logic. Furthermore, this feature can improve the resilience of the system. If an import or synchronization process fails, it can be retried without worrying about the state of the database. The system will handle duplicates, ensuring that the data eventually reaches the desired state. Overall, the ability to ignore duplicate tuples would make OpenFGA more robust, efficient, and easier to manage, particularly in large-scale deployments.

Current Workarounds and Alternatives

Currently, there aren't ideal workarounds for the problem of duplicate tuples during large-scale imports in OpenFGA. The most common approach involves checking for the existence of each tuple before writing it, which, as we've discussed, is a very slow process. This method requires querying the read API for every tuple, which adds significant overhead and can make the import process impractical for very large datasets. Another potential workaround is to implement custom logic to track which tuples have been written and avoid writing them again. However, this adds complexity to the import process and can be prone to errors. It also requires additional resources to maintain the tracking mechanism. There isn't a straightforward, efficient way to handle duplicate tuples without the proposed feature. The lack of a built-in mechanism to ignore duplicates means that organizations have to resort to less-than-ideal solutions, which can impact performance and increase the complexity of their workflows. This highlights the need for a native feature within OpenFGA that addresses this issue, making it easier for users to manage large-scale authorization data. By providing a simple and efficient way to ignore duplicates, OpenFGA can significantly improve the experience for organizations dealing with massive amounts of tuples.

The Proposed Solution: PostgreSQL's ON CONFLICT Analogy

The ideal solution being proposed draws inspiration from PostgreSQL's ON CONFLICT (...) DO NOTHING clause. This powerful feature in PostgreSQL allows you to insert data into a table and, if a conflict occurs (e.g., a duplicate key), simply do nothing. In other words, the database ignores the error and moves on to the next insert. Applying this concept to OpenFGA would mean introducing an API parameter that tells OpenFGA to ignore errors if any tuples from a batch already exist. This would streamline the tuple writing process significantly. Instead of needing to check for the existence of each tuple before writing it, the system could simply attempt to write the batch and ignore any conflicts. This approach is highly efficient because it leverages the database's built-in conflict resolution mechanism. It eliminates the need for OpenFGA to perform individual read operations for each tuple, which can be a major performance bottleneck. By adopting a similar strategy, OpenFGA can achieve a significant performance boost when handling large-scale tuple imports and reconciliation processes. This feature would not only improve the speed of these operations but also simplify the overall architecture and reduce the complexity of the code. The analogy to PostgreSQL's ON CONFLICT provides a proven and efficient model for handling duplicates, making it an excellent solution for OpenFGA.
