What a great issue report! 💯 Error 9 is EBADFD, suggesting that the kevent kq file descriptor might have been closed for whatever reason. Is it reproducible on multiple osx...

Good find! librdkafka will create a separate thread per known broker, even if it doesn't need to connect to the broker, and each such broker thread has two file descriptors...

This is handled by libserdes, can you please file an issue here: https://github.com/confluentinc/libserdes/issues/new

The most likely cause is that there is a system-installed version of vanilla libyajl that is linked instead of the one you built from source. Try uninstall the system one,...

Debian might have newer librdkafka1 packages.

We rely on avro-c to generate JSON from Avro, maybe Avro-C 1.8.x doesn't support decimal?

Thanks @krisajenkins !

That's currently not possible but could be added. Can you give an example how you would like to use this feature?

I think you might want to consider using [node-rdkafka](https://github.com/Blizzard/node-rdkafka) which wraps librdkafka.

Good work on the client and the blog post - a lot of good insight into early stage client development. :+1: You might want to try rdkafka_performance with `-X linger.ms=100`...
