Manual commit
=============

When processing more sensitive data ``enable_auto_commit=False`` mode of
Consumer can lead to data loss in cases of critical failure. To avoid it we
can commit offsets manually after they were processed. Note, that this is a
tradeoff from *at most once* to *at least once* delivery, to achieve
*exactly once* you will need to save offsets in the destination database and
validate those yourself.
When processing sensitive data, using ``enable_auto_commit=True`` (default) for the
Consumer can lead to data loss in the event of a critical failure. To avoid
this, set ``enable_auto_commit=False`` and commit offsets manually only after
messages have been processed. Note, that this is a tradeoff from *at most once*
to *at least once* delivery, to achieve *exactly once* you will need to save
offsets in the destination database and validate those yourself.
