----------------------------------------------------------------
Are there any work arounds for this limitation? We are unable to track offsets
using Kakfa Direct stream and use checkpoints. Our thinking is we need to
abandon checkpoints and manage recovery outside of Spark checkpoints while this
limitation exists.
For reference with 1.4.1, we get the following:
{{
