I agree with Emile. Null keys go to random partitions.

I thought the DefaultPartitioner would send null keys to a specific partition, but now I'm confused about whether it's actually random or not.

I practiced a similar question, and I feel like it might default to Partition 0, but I can't recall the exact reasoning behind it.

I think when the key is null, it might just go to one of the partitions randomly, like any of the topic partitions?

I remember something about how the DefaultPartitioner handles null keys, but I'm not entirely sure if it always goes to a specific partition.
