Great to see more love for using Lucene on Lambda via GraalVM native binaries! Explored that same idea few years back for my personal blog [1]. It worked pretty well, but I moved eventually away from Lambda as I wanted to close down my personal AWS account. One thing I always meant to explore was embedding the (in my case small) Lucene index directly into the binary image using Lucene's RAMDirectory via Quarkus' bytecode recording machinery, but I never got to it.
