Can we attribute some of this renewed zeal in the search space to the creation of more approachable systems languages (i.e. Golang and Rust)? Maybe I just haven't been watching the search space but I feel it wasn't always this full of new projects putting up good numbers.
There are a lot of differences between Golang and Java. As much as I dislike writing Java when I have a choice, the JVM (with Java or whatever else on top) is a very capble tool... Could you explain what you mean by there being "no pros"?
Are you maybe trying to get at the difficulty of tuning the JVM?
While I definitely agree with you on the broad strokes of the differences between rust/c++/c and java/golang (representing languages without runtimes and those with them respectively), I'd say that golang is a bit more than a java alternative if we consider more than whether a runtime is included or not.
Of course, if the only consideration is whether a runtime is there or not, golang is identical to java but also identical to common lisp or maybe even interpreted languages like python.
I do want to point out that it's possible to write horribly buggy code in c++/c (less so in rust :), which can tank performance/efficiency when compared to a java/golang program. All things considered though, the ceiling on performance and efficiency is of course higher in manual memory management land.
I watched a talk on the new indexing engine a while back:
