caveat: I'm not familiar with the clickhouse codebase. however, usually "embedding" musl libc is about portability - it allows you to build an entirely static binary that can run on practically any box. is this different?

secondly, I don't get where you're coming from faulting a columnar database for using SIMD! why is memcpy better? it comes across as, 'they worked too hard making it fast'!
