Peter Horvath commented on SPARK-26835:
---------------------------------------
This might be trivial / self-explanatory if you have been working with Spark
for a while, but for newcomers, it's a bit confusing.
Having better / more details docs is always good. :)
I've opened a pull request for this:
[https://github.com/apache/spark/pull/23742]
> 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.
