---------------------------------
Priority: Minor (was: Major)
> Log executed SQL queries
> ------------------------
>
> Key: SPARK-38915
> URL: https://issues.apache.org/jira/browse/SPARK-38915
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.2.1
> Reporter: Gérald Quintana
> Priority: Minor
>
> When Spark issues an SQL query to the database through JDBC, log (at debug or
> info level) this query in order to be able to grab it. This is useful to
> check the performance of this query, running a SQL explain plan with the
> appropriate tool.
> As SQL queries are sometimes generated, it is sometimes hard to predict what
> query Spark will sent to the database.
> Example: I would like to watch this query
