Michael Armbrust updated SPARK-18790:
-------------------------------------
Target Version/s: 2.1.0
> Keep a general offset history of stream batches
> -----------------------------------------------
>
> Key: SPARK-18790
> URL: https://issues.apache.org/jira/browse/SPARK-18790
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Reporter: Tyson Condie
>
> Instead of only keeping the minimum number of offsets around, we should keep
> enough information to allow us to roll back n batches and reexecute the
> stream starting from a given point. In particular, we should create a config
> in SQLConf, spark.sql.streaming.retainedBatches that defaults to 100 and
> ensure that we keep enough log files in the following places to roll back the
> specified number of batches:
> the offsets that are present in each batch
> versions of the state store
> the files lists stored for the FileStreamSource
> the metadata log stored by the FileStreamSink
