Should we look at improving the documentation for this? For example, for AVRO files, we have a config option to determine the compression level in https://spark.apache.org/docs/latest/configuration.html, is there a reason we also don't do that for parquet? I don't see it in the config docs or the parquet files docs: https://spark.apache.org/docs/latest/sql-data-sources-parquet.html. Or maybe we should add a link to https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/README.md? The docs also say that `spark.io.compression.zstd.level` controls the compression level for the zstd codec. Based on this, I didn't realise that this only applied to internal data. Should we make that clearer in the config? > Unable to set zstd compression level while writing parquet files > > > Key: SPARK-39743 > URL: https://issues.apache.org/jira/browse/SPARK-39743 > Project: Spark > Issue Type: Bug > Components: Spark Core >Affects Versions: 3.2.0 >Reporter: Yeachan Park >Priority: Minor > > While writing zstd compressed parquet files, the following setting > `spark.io.compression.zstd.level` does not have any affect with regards to > the compression level of zstd. > All files seem to be written with the default zstd compression level, and the > config option seems to be ignored. > Using the zstd cli tool, we confirmed that setting a higher compression level > for the same file tested in spark resulted in a smaller file. -- This message was sent by Atlassian Jira (v8.20.10#820010) - To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org

[~yeachan153]
spark.io.compression.zstd.level is adapted to
{{{}spark.io.compression.codec{}}}. It only works on internal data.
If you want to set a different zstd level to write parquet files , you can set
`parquet.compression.codec.zstd.level` in sparkConf, like :
{code:java}
val spark = SparkSession
.builder()
.master("local")
.appName("spark example")
.config("spark.sql.parquet.compression.codec", "zstd")
.config("parquet.compression.codec.zstd.level", 10) // here
.getOrCreate();
val csvfile = spark.read.csv("file:///home/test_data/Reviews.csv")
csvfile.coalesce(1).write.parquet("file:///home/test_data/nn_parq_10"){code}
