Navigating Auth0 Rate Limits in Our Admin Portal

TL;DR

• Auth0 rate limits are a challenge when fetching user data for our admin portal.
• Implemented multiple iterations to navigate the constraints.
• Developed a custom rate-limiting class to manage API call throttling.
• Current solution is functional for now but lacks scalability.

Building our admin portal with seamless data integration across multiple services sounded straightforward, but reality threw a curveball, specifically with rate limits imposed by Auth0—our authentication provider. Let’s dissect this technical conundrum and the solutions we attempted.

Initial Approach: Direct User Retrieval

My first instinct was simple: query our database for user IDs, then retrieve user roles and details from Auth0 using its Lucene query syntax. However, problems arose quickly:

• Auth0 limits each query to 4096 characters, forcing us into multiple requests.
• Upon hitting a few dozen users, we already encountered Auth0’s rate cap of two requests per second.

Second Attempt: Role-Based Querying

After hitting the initial roadblock, the next iteration took life—fetch roles and then ascertain associated users. This strategy marginally extended how much data we could pull:

• Decreased likelihood of rate limit infarcts by reducing request numbers.
• Nonetheless, complexities in data reassembly and backend performance plagued this approach, capping at about 60-70 users.

The Rate Limiting Class: A Middleware Solution

The pivotal decision: tackle rate limiting directly. Researching Auth0’s docs, I crafted a rate-limiting class, a universal wrapper for our API calls:

• Recorded and queued calls, deduplicating queued calls.
• Managed execution timing to respect Auth0’s rate replenishment.
• Resulted in the ability to handle a couple of hundred users—though sluggish.

Conclusion:

Our journey with Auth0’s formidable rate restrictions has taken us through a problem-solving maze. The rate limiting class serves as a temporary solution, satisfying our current user volume requirements. However, with potential growth, it remains clear that scalability issues need addressing. The search for alternative methods or possibly re-evaluating our authentication storage strategies is ongoing, as we aim to secure a resilient, scalable system for the future. Until then, we make do with what we have, preparing for the odyssey ahead.
