-----------------------------------
Summary: Fix the reported start offsets in streaming query (was: Fix the
reported start and end offsets in streaming query)
> Fix the reported start offsets in streaming query
> -------------------------------------------------
>
> Key: SPARK-24697
> URL: https://issues.apache.org/jira/browse/SPARK-24697
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.3.1
> Reporter: Arun Mahadevan
> Priority: Major
>
> Streaming query reports progress during each trigger (e.g. after runBatch in
> MicrobatchExcecution). However the reported progress has wrong offsets since
> the offsets are committed and committedOffsets is updated to the
> availableOffsets before the progress is reported.
> This leads to weird progress where startOffset and endOffsets are always the
> same.
> Sample output for Kafka source below. Here 11 rows are processed in the
> microbatch however the start and end offsets are same.
