Subject [jira] [Created] (SPARK-19525) Enable Compression of Spark Streaming Checkpoints
Date Thu, 09 Feb 2017 00:55:41 GMT
Aaditya Ramesh created SPARK-19525:

             Summary: Enable Compression of Spark Streaming Checkpoints
                 Key: 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.
