Window Support in Flink

nsengupta
Hello Flinksters,

I have come across two terms in this presentation: http://www.slideshare.net/sbaltagi/flink-vs-spark

(a) Hopping Windows
Could someone please exemplify or point to a link which explains, what is this?

(b) Native support for integrated datastore
Is this referring to the various 'Sink's that Flink comes ready with it? If not, what is this referring to?

TIA

Hey!

(a) This is not a Flink term. I could not find the term in the slides,
but I guess that it is referring to tumbling windows. For more
details, check out these pages:

https://flink.apache.org/news/2015/12/04/Introducing-windows.html

https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/streaming/windows.html

(b) I am not sure what the slides are exactly referring to, but I
would guess that it's either referring to
- the pluggable state backends which are used to store the state of
windows and user functions
(https://ci.apache.org/projects/flink/flink-docs-release-1.0/apis/streaming/state_backends.html)
- the supported sources and sinks, which allow to read and write
various data stores

AW: Window Support in Flink

Fabian Hueske-2

Hopping windows is a term used on the Apache Calcite website [1]. In Flink terms, hopping windows are sliding windows.

 

Cheers, Fabian

Hello Ufuk <[hidden email]>,

The term 'hopping windows support' can be found in Slide 24 of the deck.

In any case, You and Fabian have clarified. So, many thanks.
