An implicit sentiment of the post is how hard "big data jvm" systems are to learn and work with, as an individual developer. The open source tools of old were all "apt install" and begin. These "ageing modern" big data systems were hacked together on the massive data centres of internet giants and very poorly packaged for use anywhere else. This has created high barriers to entry for would-be junior data engineers. I support any system, eg., this one, which brings back this ability to scale naturally up from a one-dev-machine prototype.
