rust/c++/c has no gc and better performance/efficiency compared to java/golang. so you get excited for a library/db in those languages

golang is kinda a java alternative. a db/search-engine in java/golang kinda sucks (it will under pressure)

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.

Thanks for clarifying what you meant!
