Librdkafka integration on embedded device

[nikidimitrow]

Hello support team,

I'm try to run librdkafka (as a Kafka consumer) on the microcontroller ESP32 (https://www.espressif.com/en/products/socs/esp32)

As microcontroller are well know for small flash memory and CPU power compare with desktop PC my questions are following:

• Is there a version of librdkafka for embedded device?
• Some bare minimal and fully strip from desktop variants of the project?
• Somebody already did something similar?
• In your opinion is it possible to be perform integration in librdkafka on embedded device?

Excuse me for so general questions.

Have a great evening and cold beers.

librdkafka requires posix threads, multiple cores, and megabytes of memory, so it will not run on an ESP32 or similar.
I recommend using a simple MQTT or HTTP client on the ESP32 and an MQTT connector or the Kafka REST proxy on the serer side to bridge between the embedded devices and Kafka.

Posix Threads are available.
Many Megabytes of RAM not .

Espressif had confirm the statement of @edenhill, that integration of librdkafka is not possible on IoT device: espressif/esp-idf#8848 (comment)
