Online classes for spark topics

[ashok34...@yahoo.com.INVALID]

Hello gurus,
Does Spark arranges online webinars for special topics like Spark on K8s, data 
science and Spark Structured Streaming?
I would be most grateful if experts can share their experience with learners 
with intermediate knowledge like myself. Hopefully we will find the practical 
experiences told valuable.
Respectively,
AK
