   @ijuma Thanks for the patch. I think the change makes sense. Part of me is inclined to drop the logic for immediate propagation of high watermark entirely. Instead, we could say propagation is bounded by the max wait time which users could potentially tune for their own needs. Otherwise enabling this feature becomes sort of risky. We just need to be a little careful to ensure that the partition still gets included in the fetch response if there is a high watermark update. I'll open a JIRA and we can discuss this separately.
