----------------------------------------
We have a patch that works for an older version. I am currently trying to port
it to Spark 2.1.0. Is this okay?
> Enable Compression of Spark Streaming Checkpoints
> -------------------------------------------------
>
> Key: SPARK-19525
> URL: https://issues.apache.org/jira/browse/SPARK-19525
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 2.1.0
> Reporter: Aaditya Ramesh
>
> In our testing, compressing partitions while writing them to checkpoints on
> HDFS using snappy helped performance significantly while also reducing the
> variability of the checkpointing operation. In our tests, checkpointing time
> was reduced by 3X, and variability was reduced by 2X for data sets of
> compressed size approximately 1 GB.
