> Flag to close Write Ahead Log after writing
> -------------------------------------------
>
> Key: SPARK-11324
> URL: https://issues.apache.org/jira/browse/SPARK-11324
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Reporter: Burak Yavuz
>
> Currently the Write Ahead Log in Spark Streaming flushes data as writes need
> to be made. S3 does not support flushing of data, data is written once the
> stream is actually closed.
> In case of failure, the data for the last minute (default rolling interval)
> will not be properly written. Therefore we need a flag to close the stream
> after the write, so that we achieve read after write consistency.
