Oran Hirsch, R&D Big Data Developer, Dynamic Yield
“Since Scylla tunes itself to the workload, we just set the host IP, cluster name, seeds, and let it go.”
Hang Chan, Site Reliability Engineer, Dstillery
“The system requires less management and configuration to keep it running. Scylla just runs smoothly and with minimal configuration.”
Amit Ziv-Kenet, Backend Tech Lead, Augury
“We have observed a huge reduction in read latency by migrating from Cassandra to Scylla which enabled us to easily meet our SLAs.”
Andrew Katz
CTO & Founder, mParticle
“What I like most about Scylla is the latency it gives us, no matter what traffic is, no matter what happens it’s just a straight line. No spikes, no weird behaviors.”
“We evaluated Cassandra and Dynamo. We found Scylla had the best performance for the TCO and without vendor lock-in.”
Sam Kenkel, DevOps Lead, Meshify
“After running a production cluster of Scylla for a year, I just cannot stress this enough; I sleep very well without worrying that something might go wrong.”
Meraj Rasool, DevOps Lead, SkyElectric
Compose, an IBM company, allows developers to get production-ready databases in minutes. Developers can choose the best OSS database technologies to power their applications and let Compose do the heavy lifting behind the scenes.
“When we heard of a Cassandra drop-in-replacement we were skeptics. But very quickly we found it is all true—not only were the latency and GC issues completely gone, better hardware utilization allowed us to shrink the cluster size by half!”
Gabriel Mizrahi
CTO, Investing.com
“Scylla is the ideal database for IOT in the industry right now.”
Doug Stuns, Scylla Architect, GPS Insight

Felipe Moz, Big Data Engineer, Natura
“Since Scylla did very well out of the box, we ended up spending a lot of time on other databases—mainly Hbase and Cassandra—to make them more comparable to Scylla. But of course we failed miserably. They still don’t perform as well as Scylla.”
Ted Chang and Chin Huang

FengLin (MengYe Shen), Mogujie
“We have a 47-node cluster across 5 data centers. With ScyllaDB we were able to reduce hardware cost and achieve great throughput and latency. Had we used Apache Cassandra for the same use case, we estimated that the cluster would have been at least twice as large.”
Andrew Sweeney, VP of Engineering at AppNexus
“One of my favorite aspects about Scylla is how it’s written. It’s self-tuning and looks at the hardware and that saves administrators time greatly. And you get a product that does what it’s supposed to do without having to be a leading authority on the topic.”
