Blog post about Parallel Joins in Flink - Mechanisms and Performance

[Stephan Ewen]

Hello Squirrels!

Flink committer Fabian Hueske has written a very nice article about joins
in Apache Flink.

The article talks about joins in the APIs, the join algorithms, memory
management, and performance experiments on a small cluster.
A good read for everyone with SQL/ETL-style use cases and for those who are
interested to learn more about how Flink works.

Great post.

Small comment, @Fabian I think the image is flipped.
The image for Repartition-Repartition is shown in the Broadcast-Forward section.
