[jira] [Commented] (SPARK-26835) Document configuration properties
of Spark SQL Generic Load/Save Functions
[ https://issues.apache.org/jira/browse/SPARK-26835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16762431#comment-16762431 ]
Hyukjin Kwon commented on SPARK-26835:
--------------------------------------
They are explained in API documentation. "Generic Load/Save Functions section of Spark SQL documentation " is like a general guide. It doesn't necessarily document everything.
CSV documentation isn't there due to documentation duplication concern.
Please go ahead and fix it if you're willing to do. Otherwise, I would leave this just closed to leave only active JIRAs. All the documentations can be improved in all the ways.
> Document configuration properties of Spark SQL Generic Load/Save Functions
> --------------------------------------------------------------------------
>
> Key: SPARK-26835
> URL: https://issues.apache.org/jira/browse/SPARK-26835
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Peter Horvath
> Priority: Major
>
> Currently the [Generic Load/Save Functions section of Spark SQL documentation|https://spark.apache.org/docs/2.4.0/sql-data-sources-load-save-functions.html]
> does not explain the available configuration properties at all.
> Neither the available formats nor their configuration properties are listed properly: there are some usage samples, but that is really.
> For some formats, there is a remark to visit the site of the provider; quote: "_To find more detailed information about the extra ORC/Parquet options, visit the official Apache ORC/Parquet websites."_
> However, this is not applicable for all format providers; for example there is not even a hint regarding the CSV writer's configuration properties or where they can be looked up.
> Please add documentation regarding the configuration properties. Either copy over documentation completely, or link.
