> Investigate using cloudflare's zlib library
> -------------------------------------------
>
> Key: IMPALA-11603
> URL: https://issues.apache.org/jira/browse/IMPALA-11603
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 4.2.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> Amazon recommends the use of cloudflare's zlib implementation at
> [https://github.com/cloudflare/zlib]
> In a blog post, they claim pretty large performance boosts over the regular
> zlib implementation:
> [https://aws.amazon.com/blogs/opensource/improving-zlib-cloudflare-and-comparing-performance-with-other-zlib-forks/]
> {noformat}
> On Arm:
> Compression performance: ~90 percent faster than zlib-madler (original
> zlib).
> Decompression performance: ~52 percent faster than zlib-madler.
> On x86:
> Compression performance: ~113 percent faster than zlib-madler.
> Decompression performance: ~44 percent faster than zlib-madler.{noformat}
> The blog post is a year and a half old, so things may have changed since
> then, but it seems interesting. Amazon's guidebooks still recommend it.
