Any suggestions are welcome. 🙌
Made some progress on Hookkeeper today.
Load-tested it with 50K requests, explored delivery statistics in Neon, and ran into Upstash's 500K request limit
Now figuring out the deployment setup for the BullMQ worker and public webhook destinations
Still a few things to iron out!
Today I learned something new while exploring retries and rate limiting in my webhook system.
When many failed jobs retry at once, they can overload a service. That's the thundering herd problem.
Jitter adds randomness to retry delays, spreading the load over time.
why the hell is auto-scroll still not available on Instagram for iPad, @instagram ? 😭
it's 2026. how am i still manually scrolling reels?
Today I learned about database Connection Pooling.
Instead of opening and closing a database connection for every request, we maintain a pool of reusable connections.
Also learned why managing these pools becomes important when an application runs multiple backend instances.
↳ Each backend instance can have its own connection pool.
For example, 4 instances with 30 connections each can create 120 potential connections, even if the database allows only 100.
↳ What happens when all connections are occupied?
New requests have to wait until a connection becomes available. If they wait too long, they can time out.
↳ A request borrows an available connection, executes its database query, and returns the connection to the pool.
Another request can then reuse that same connection instead of creating a new one.
Learning System Design:
Spent some time learning about ACID today. The bank transfer example actually helped me understand why these properties matter.
A simple transfer involves more than just moving money from one account to another.
