How to show full column content in a Spark Dataframe?

Question

I am using spark-csv to load data into a DataFrame. I want to do a simple query and display the content:

val df = sqlContext.read.format(\"com.databricks.spa         


        

Answer 1

In c# Option("truncate", false) does not truncate data in the output.

StreamingQuery query = spark
                    .Sql("SELECT * FROM Messages")
                    .WriteStream()
                    .OutputMode("append")
                    .Format("console")
                    .Option("truncate", false)
                    .Start();
