Grouping in Spark Streaming / batch size = time window?

[Daniela S]

Hi,

 

I am a newbie in Spark Streaming and have some questions.

 

1) Is it possible to group a stream in Spark Streaming like in Storm (field grouping)?

 

2) Could the batch size be used instead of a time window?

 

Thank you in advance.

 

Regards,

Daniela
