Hi, I progressed a bit in the above mentioned topic - 1) I am feeding a CSV file into the Kafka topic. 2) Feeding the Kafka topic as readStream as TD's article suggests. 3) Then, simply trying to do a show on the streaming dataframe, using queryName('XYZ') in the writeStream and writing a sql que

Re: Multiple Kafka Spark Streaming Dataframe Join query

Relevant: https://databricks.com/blog/2018/03/13/introducing-stream-stream-joins-in-apache-spark-2-3.html This is true stream-stream join which will automatically buffer delayed data and appropriately join stuff with SQL join semantics. Please check it out :) TD On Wed, Mar 14, 2018 at 12:07

Re: Multiple Kafka Spark Streaming Dataframe Join query

I misread it, and thought that you question was if pyspark supports kafka lol. Sorry! On Wed, Mar 14, 2018 at 3:58 PM, Aakash Basu wrote: > Hey Dylan, > > Great! > > Can you revert back to my initial and also the latest mail? > > Thanks, > Aakash. > > On 15-Mar-2018 12:27 AM, "Dylan Guedes" wro

Re: Multiple Kafka Spark Streaming Dataframe Join query

Hi, I'm yet to. Just want to know, when does Spark 2.3 with 0.10 Kafka Spark Package allows Python? I read somewhere, as of now Scala and Java are the languages to be used. Please correct me if am wrong. Thanks, Aakash. On 14-Mar-2018 8:24 PM, "Georg Heiler" wrote: > Did you try spark 2.3 wi

Did you try spark 2.3 with structured streaming? There watermarking and plain sql might be really interesting for you. Aakash Basu schrieb am Mi. 14. März 2018 um 14:57: > Hi, > > > > *Info (Using):Spark Streaming Kafka 0.8 package* > > *Spark 2.2.1* > *Kafka 1.0.1* > > As of now, I am feeding pa
