Window Support in Flink

[Nirmalya Sengupta <se...@gmail.com>]

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

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

Cheers, Fabian

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://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
