Hi all,
In case anyone is interested, I started a blog [1] this year about big
data technologies. There are 8 articles so far and they are mainly
related to Beam even if some are related to Spark (but with the
knowledge acquired while working on the Beam Spark runner).
I just published the first blog article of a serie of articles about
tricky use cases of Apache Beam. This one is about incremental join,
next one will be about custom combine and the last of the serie about
custom window.
