 ### Storing Offsets
-Kafka delivery semantics in the case of failure depend on how and when offsets are stored.  Spark output operations are [at-least-once](streaming-programming-guide.html#semantics-of-output-operations).  So if you want the equivalent of exactly-once semantics, you must either store offsets after an idempotent output, or store offsets in an atomic transaction alongside output. With this integration, you have 3 options, in order of increasing reliablity (and code complexity), for how to store offsets.

 #### Checkpoints
 If you enable Spark [checkpointing](streaming-programming-guide.html#checkpointing), offsets will be stored in the checkpoint.  This is easy to enable, but there are drawbacks. Your output operation must be idempotent, since you will get repeated outputs; transactions are not an option.  Furthermore, you cannot recover from a checkpoint if your application code has changed.  For planned upgrades, you can mitigate this by running the new code at the same time as the old code (since outputs need to be idempotent anyway, they should not clash).  But for unplanned failures that require code changes, you will lose data unless you have another way to identify known good starting offsets.
