Limit Number Of Request Environments In Generated Schema

by ADMIN 57 views

Introduction

In the process of generating schema, it is crucial to consider the potential impact on performance. One aspect that can significantly affect the speed of validation is the number of request environments that can be defined. In this article, we will discuss the importance of limiting the maximum number of request environments that can be generated by a schema.

The Problem of Excessive Request Environments

While it is not a common occurrence, there are instances where the appliesTo lists for actions in the schema can become quite extensive. This can lead to the generation of a large number of request environments, as each principal and resource applies to list contributes to the total count. The result is a significant increase in the number of request environments, which can, in turn, cause slow units when validating policies in every defined environment.

The Consequences of Unchecked Request Environments

The issue of excessive request environments can have far-reaching consequences, particularly when it comes to performance. As the number of request environments grows, so does the time required to validate policies. This can lead to a decrease in productivity and an increase in frustration, especially for users who rely on fast and efficient validation processes.

The Importance of Setting a Reasonable Limit

While it is essential to set a limit on the number of request environments, it is equally important not to set it too low. A limit that is too restrictive can hinder the testing process, making it difficult to validate policies in a realistic and comprehensive manner. On the other hand, a limit that is too high can lead to performance issues and slow units.

A Suggested Approach

To strike a balance between testing and performance, we propose setting a reasonable limit on the number of request environments that can be generated by a schema. This limit should be high enough to accommodate realistic testing scenarios, yet low enough to prevent performance issues.

Alternatives Considered

While there are various approaches to addressing the issue of excessive request environments, we have considered the following alternatives:

  • Increasing the computational resources: While this may provide a temporary solution, it is not a sustainable or scalable approach.
  • Optimizing the schema generation process: This could involve improving the algorithms used to generate request environments or reducing the number of principal and resource applies to lists.
  • Implementing a request environment cache: This could help reduce the number of request environments generated by storing frequently used environments in a cache.

Conclusion

In conclusion, limiting the number of request environments in generated schema is a crucial step in ensuring the performance and efficiency of the validation process. By setting a reasonable limit, we can strike a balance between testing and performance, making it possible to validate policies in a fast and efficient manner.

Recommendations

Based on our analysis, we recommend the following:

  • Set a reasonable limit on the number of request environments that can be generated by a schema.
  • Ensure that the limit is high enough to accommodate realistic testing scenarios.
  • Consider implementing a request environment cache to reduce the number of generated environments.

Future Work

In the future, we plan to:

  • Investigate alternative approaches to addressing the issue of excessive request environments.
  • Implement a request environment cache to improve performance.
  • Continuously monitor and optimize the schema generation process to ensure the best possible performance.

Describe the feature you'd like to request

We should limit the maximum number of request environments that can be defined by a generated schema.

While it doesn't happen often, we can rarely generate long appliesTo lists for actions in the schema. A schema with large appliesTo lists can quickly generate a very large number of request environments because request environments are computed from the product of principal and resource applies to lists. This can lead to slow units when we need to validate a policy in every defined request environment.

We shouldn't set this limit too low since it is interesting to test at ~100 environments, but previous slow units were found in the rare case of a schema ~10000 request environments.

Describe alternatives you've considered

  • Increasing the computational resources: While this may provide a temporary solution, it is not a sustainable or scalable approach.
  • Optimizing the schema generation process: This could involve improving the algorithms used to generate request environments or reducing the number of principal and resource applies to lists.
  • Implementing a request environment cache: This could help reduce the number of request environments generated by storing frequently used environments in a cache.
