Is this generated data actual data or you are testing the application?

Sounds like a form of Lambda architecture here with some decision/processing 
not far from the attached diagram

Ok so you want to generate some random data and load it into Kafka on a regular

I want to get some data from REST API requests in real time and consider to

And then put it to Kafka.
I can't realise how to create streaming dataframe from generated data.

Fwd: the life cycle shuffle Dependency

2023-12-27 Thread yang chen 
hi, I'm learning spark, and wonder when to delete shuffle data, I find the
ContextCleaner class which clean the shuffle data when shuffle dependency
is GC-ed.  Based on source code, the shuffle dependency is gc-ed only when
active job finish, but i'm not sure,  Could you explain the life cycle of a
Shuffle-Dependency?

Is it possible to write pyspark UDF, generated data to streaming dataframe?
I want to get some data from REST API requests in real time and consider to 
save this data to dataframe.
And then put it to Kafka.
I can't realise how to create streaming dataframe from generated data.
