@Dzeri96, setting `spark.io.compression.codec=zstd` could be an option. Generally, with default `spark.io.compression.zstd.level=1`, for shuffle cases, compression ratio zstd:lz4 is about 2:1, which means you are expected to save 50% shuffle IO and disk space with zstd, but note that zstd will use more CPUs, so if you run micro benchmark where IO is not a bottleneck, you will see performance drop after switching to zstd, but for large scale production cluster, I suppose zstd is a better option, for both performance and bills. -- This is an automated message from the Apache Git Service.
