ScyllaDB Migration: How to design high throughput and low latency NoSQL deployments

Yuan Ren, Head of Data Science at mParticle, discusses our ScyllaDB migration and how to process 50 billion monthly messages via NoSQL deployments.

mParticle processes and relays incoming messages in near real time, and thus requires a data store that supports querying historical data as well as storing incoming data streams with low latencies. Read on to learn about our ScyllaDB migration and tips for designing high throughput and low latency NoSQL deployments.

mParticle’s ScyllaDB migration:

We initially built the system on top of Apache Cassandra, but as the business grew, we struggled to tune the cluster to keep up with our growing data ingestion rate. Scylla, the next generation of Cassandra, helped us meet our SLA requirements without having to forego the benefits we love from Cassandra. With Scylla’s auto-tuning capability, we can focus our engineering efforts on building products instead of cluster performance.

Check out the corresponding SQL NYC, The NoSQL & NewSQL Database Meetup materials below to learn:

  • How to stop worrying about mix workloads, read-modify-write, compaction and tuning
  • Why mParticle decided on the Apache Cassandra to ScyllaDB migration, an open source database that is fully compatible with Apache Cassandra
  • How to more effectively utilize high capacity Amazon Web Services (AWS) hardware, including the 64 vcpu, 15TB NVMe i3.16xl instances to run a 100TB dataset with just 10 nodes

The mParticle platform captures more than $5 billion in e-commerce transactions over 1 billion monthly active users. Despite its challenging workload, with read-modify-write patterns on huge payload and strict read latency SLAs, we are able to achieve breakneck throughput and low latency without compromising on global database availability….With a little help from our ScyllaDB migration, of course.
