Original Summary

I recently built and released an in-memory B+Tree library for the JVM, mainly because I wanted to explore the cache-locality and GC overhead issues of pointer-heavy Red-Black Trees.When it finally compiled and started wining over TreeMap in JMH benchmarks, I thought I was basically done.<p>Turns out, not even close.<p>Over the last few weeks I went down a rabbit hole of:<p>- Jqwik property-based testing with 214,000+ randomized structural cases. - Serialization compatibility and serialVersionUID. - JFR and -Xlog:gc to figure out whether some benchmark results were actually anomalies. - Strictly following JDK SortedMap contracts instead of taking optimization shortcuts. - added Jacoco coverage(95.9%) and Codecov(91%) - Trying every possible way and optimization if needed - looped massive time Otimization-&gt;Correctness-&gt;Bencmark-&gt;reoptimization and the loop goes until it reaches maximum state. The final result was a 30~46% memory saving and 2x (sometimes up to 10x) speedup. Maven Central shows 1.7K, 154 unique sources and 47 downloads, though I suspect a lot of that is just CI&#x2F;CD caching.<p>And it made me ask:<p>For people who actually evaluate open-source dependencies at companies, what is your checklist? At what point do you look at a solo developer&#x27;s GitHub repo and think, &quot;Yeah, I&#x27;d be comfortable putting this in production&quot;?
