optimization-engine VS rust-rdkafka

optimization engine

I found this library here called the optimization engine . While it looks really good and thorough, I don't believe it is as feature rich as the C++ Ceres Solver. But mabye there are other libraries out there that people know of which could complement?

C++ has a lots of good libraries for nonlinear optimization such as Ceres-solver, lpopt, ifopt and so on. I was wondering if anyone know any similar alternatives in Rust? I found this optimization engine https://github.com/alphaville/optimization-engine library which at first glance seems to have fairly good documentation and also a couple of active developers (last commit to master 16.April). Anyone has experience with this library? If so, what's good and what's not. Any limitations?

I use this library a lot and it's got some nice touches for how to handle wrapping a C library: https://github.com/fede1024/rust-rdkafka

For this example, we're using rdkafka to build producers and consumers, because it allows us to specify custom headers for each record.

I am playing with tokio and rust-rdkafka library, following the examples like this one: https://github.com/fede1024/rust-rdkafka/blob/6fb2c37/examples/asynchronous_processing.rs

The source for the current version of the library can be found on Github. I had to increase the major version because I needed to break the API in order to support all formats supported by the current Schema Registry version. I also added the possibility to set an API key, so it can be used with Confluent Cloud, the cloud offering from Confluent. As part of the latest major refactoring it's also supporting async. This might improve performance of your app, and is also the default for the major Kafka client, more information about why you would want to use async can be found in the async book. The schemas retrieved from the Schema Registry are cached. This way the schema is only retrieved once for each id, and reused for other messages with the same id.

What's wrong with rust-rdkafka?

This is a two-part series to help you get started with Rust and Kafka. We will be using the rust-rdkafka crate which itself is based on librdkafka (C library).
