node-rdkafka VS librdkafka

Open producer.ts to see the code you need to send the data to an Apache Kafka topic. To work with Apache Kafka you can use one of the existing client libraries, there are several options available. This project uses node-rdkafka, which is a NodeJS wrapper for the Kafka C/C++ library. Check its GitHub repository Readme for installation steps.

Apache Kafka seemed to work very well with node.js in the beginning. node-rdkafka performed really well (https://github.com/Blizzard/node-rdkafka -> wrapper for librdkafka) .

And some native modules, like node-rdkafka will spawn threads of their own.

If you're using Kafka in a Node.js app, it's likely that you'll need node-rdkafka. This is a library that wraps the librdkafka library and makes it available in Node.js. According to the project's README, "All the complexity of balancing writes across partitions and managing (possibly ever-changing) brokers should be encapsulated in the library."

But what about Kafka producer clients in other languages? The excellent librdkafka project is a C/C++ implementation of Kafka clients and is widely used for non-JVM Kafka applications. Additionally, Kafka clients in other languages (Python, C#) build on top of it. The default partitioner for librdkafka uses the CRC32 hash function to get the correct partition for a key.

We could have made some changes at the librdkafka level (see this), but we didn’t really want to pursue this (at least not yet).

You want records with the same key to always land on the same partition, so you need all the clients to use the same hashing algorithm. The easiest way to do that is to make sure the librdkafka client uses the java compatible murmur2_random hash algorithm. See “Partitioner” section here: https://github.com/confluentinc/librdkafka/blob/master/CONFIGURATION.md

As my first "real world" (ish) project in Vlang, I'm trying to copy https://github.com/confluentinc/confluent-kafka-go, which is a Go wrapper for Kafka C client library, https://github.com/edenhill/librdkafka
