package debug
Contains methods for debugging query execution.
Contains methods for debugging query execution.
Usage:
```
import org.apache.spark.sql.execution.debug._
sql("SELECT 1").debug()
sql("SELECT 1").debugCodegen()
```
or for streaming case (structured streaming):
```
import org.apache.spark.sql.execution.debug._
val query = df.writeStream.<...>.start()
query.debugCodegen()
```
Note that debug in structured streaming is not supported, because it doesn't make sense for streaming to execute batch once while main query is running concurrently.
