Re: Is there a mutable dataframe spark structured streaming 2.3.0?
Quick Question regarding the same topic. If construct the data frame *df* in the following way key | value | topic| offset | partition | timestamp foo1 | value1 | topic1 | ... foo2 | value2 | topic2 | ... what happens when I do df.writeStream().format("kafka").option("topic", "hello_topic").start() ? Will it use the hello_topic specified in the option or the topic from row ? Sure I don't need to specify topic as an option if I have it in a row but I wonder what happens internally if this is the case? Thanks!

DataFrames are not mutable.

Hey, I faced the same issue a couple of days back, kindly go through the mail chain with "*Multiple Kafka Spark Streaming Dataframe Join query*" as subject, TD and Chris has cleared my doubts, it would help you too.

Hi All, Is there a mutable dataframe spark structured streaming 2.3.0? I am currently reading from Kafka and if I cannot parse the messages that I get from Kafka I want to write them to say some "dead_queue" topic. I wonder what is the best way to do this? Thanks!
