I just released version v0.7.4 of SRClient, a Go client for Schema Registry. This is a library that I created almost 6 years ago, and it is still helpful for Go developers building apps for Kafka.

LLMs' fanciness and increasing intelligence don't change the reality—ultimately, they're just API calls. As such, they suffer from the same problems as API calls, such as throttling, timeouts, and exponential delays. 🔌 ⚡️
➡️ But you can use clever ways to make LLM calls faster.

Everybody's putting AI in their apps. They're stringing APIs together and sending the results down to the browser. But those APIs are expensive, the round trips are long, and there's a lot of data being exposed.
Maybe there's a better way?
