Please critque the hashtable that is now fixed and works.
You should check out uthash, which has an extensive test suite and documentation (the user guide), to see how a library like this one that's used in the real world is written, tested, and used: https://github.com/troydhanson/uthash/tree/master/tests

A Critical Detail about Kafka Partitioners
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.

Horizontally scaling Kafka consumers with rendezvous hashing
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).

Events with same key going to different partitions
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

Getting sum type values from a map

Installing node-rdkafka on M1 for use with SASL
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."
