Re: [DISCUSS] CEP-49: Hardware-accelerated compression

[Jeff Jirsa]

One perpetual challenge with customizing codebase for  dedicated hardware is ongoing support / testing / maintenance followed by ensuring vendor agnostic / neutral access QAT is one of those things that’s great for a set of people paying for it, but I don’t know any current contributors who have access - does anyone not at Intel actually have access to QAT or does intel expect to use this in production yourselves (are you running a cluster where this fix improves your life or are you proposing this as a way to benefit your customers, or both)?  On Jun 5, 2025, at 11:52 AM, Kokoori, Shylaja <shylaja.koko...@intel.com> wrote:  Hi everyone,   We would like to propose hardware accelerated compression in Cassandra, CEP-49: Hardware-accelerated compression As load on Cassandra servers increase, performance of compress/decompress operations starts becoming a bottleneck. Our goal via this CEP is to offload these operations to dedicated hardware accelerators and free up the CPUs.   We'd really appreciate your feedback on this proposal.   Thank you, Shylaja
