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.

CodegenMode

case object CodegenMode extends ExplainMode with Product with Serializable

Codegen mode means that when printing explain for a DataFrame, if generated codes are available, a physical plan and the generated codes are expected to be printed to the console.
