Hello everyone! Does lakeFS have any tutorials or training lessons/videos to help understand how it works and its intricacies?

https://docs.lakefs.io/latest should get you started..the YouTube channel should holds more gems.

@Nikolai Potapov - you can also benefit from our samples.

I did try the latest example and it works. Currently I am using standalone lakefs on-prem. I tried kafka example mentioned in samples and it just fails https://github.com/treeverse/lakeFS-samples/tree/main/01_standalone_examples/kafka When we try to create test_connector in kafka connect it fails with following logs
