Scylla Open Source Roadmap

ScyllaDB is an open source first company committed to shared innovation and transparency that leads to continually improving the features of its NoSQL database

This page is a point-in-time snapshot of our current efforts and plans. However, our plans are always responsive to customer input, market evolution, and development constraints of database technologies.

Track progress through the open source Scylla project on GitHub including a public project issue tracker. You are welcome to add database feature requests and vote for your favorite issue.

We have an additional set of advanced NoSQL database features that go beyond Apache Cassandra, for example:

  • Shard-per-core design for more linear performance
  • Heat-weighted load-balancing
  • Seedless gossip implementation
  • CPU and I/O schedulers
  • CQL queryable Change Data Capture (CDC)
  • AWS DynamoDB compatible API (Alternator)
  • and more!

Scylla Open Source Release Cycle

Scylla Open Source uses a familiar X.Y.Z release numbering scheme, with X being the major release, Y being the minor release and Z being the maintenance or bug fix release.

Scylla major releases have historically been made available roughly every year and a half. Between major releases we release periodic Scylla minor versions, which include both bug fixes and new features. We support only the two latest minor releases. So, for example, if we released Scylla Open Source X.3, we would support X.3 and X.2; X.1 would no longer be supported. We produce bug fix-only (“.Z”) releases regularly between minor releases.

Complex features for more advanced database architectures will be flagged as experimental for one release, marking them as completed, but not thoroughly tested yet. Also, some experimental features may be subject to change as we discover how it performs in customer environments. At the same time, we put most of our effort into internal optimizations and performance improvements. You can read more about all the rigors we put Scylla through on our testing page.

Scylla is moving fast! Keep an eye on the scylladb-users mailing list for updates and find out how else you can get involved in our Scylla Open Source community.

Planned features for Scylla Open Source 4.x and 5.x

  • Enhancements to our DynamoDB compatible API (Alternator)
  • Faster resumable streaming (Repair base streaming)
  • Transactional schema updates based on Raft
  • Transactional topology change (allows adding or removing multiple nodes simultaneously) based on Raft
  • Tablets
  • Better overload protection
  • Lua / WebAssembly UDF
  • And many more stability and performance improvements

We are invested in improving database technologies in 2021 and beyond, including an improved disk format, different database enhancements and integration with analytics and search.

Scylla Manager Roadmap

Scylla Manager is a centralized, highly available, NoSQL database management solution for multiple Scylla clusters. It is part of the Scylla Enterprise offering and is also available to Scylla Open Source users (limited to 5 nodes).

Scylla Manager 2.x now includes recurrent backups to AWS S3 and a new Scylla Agent.

While the list below includes advanced database management features visible to the users, we put most of our effort into under the hood optimizations, performance improvements, and autonomous database functionality.

Planned Scylla Manager 2.x features:

  • Backup to more targets – 2.x
  • Automated restore and clone – 2.x
  • Time Window support – 2.x
  • Cluster Management – Scylla Manager 3.0 (basic), 3.1 (extended)
  • Alerts Manager – Scylla Manager 3.x
  • Log Collection – Scylla Manager 3.x
  • Manager Role-Based Access Control – Scylla Manager 3.x
  • UI console – Scylla Manager 3.x
  • Scylla-as-a-Service – cloud-based database management system

Scylla Monitoring Stack Roadmap

Scylla Monitoring Stack is a bundle of three components (a Prometheus metric collector, alert manager, and Grafana 6 dashboards) that can be deployed as containers or directly onto a host. It collects metrics and events through the Scylla Agent from nodes and from Scylla Manager.

The stack empowers DevOps, Infrastructure Operations, and Database Administrators to quickly find and fix issues impacting the performance of their Scylla cluster. Teams can drill down from high-level dashboards to detailed metrics to determine next steps.

Scylla Monitoring 3.2 introduces dashboard annotations for repair and backup as well as a new collection of dashboard screens.

Planned Scylla Manager 3.x features:

  • Support monitoring of future version of Scylla, Scylla Enterprise and Scylla Manager
  • Add annotations for Cluster wide operation
  • Unified packaging and operation with Scylla Manager

Scylla Operator Roadmap

Scylla Operator (Preview) is a new tool for automating the deployment of Scylla clusters within a kubernetes environment. It currently it supports:

  • Deploying across multi-zone clusters
  • Scaling up clusters or adding new racks
  • Scaling down clusters
  • Monitoring with Prometheus and Grafana

Planned Scylla Operator features:

  • Fully install Scylla and Scylla Enterprise Clusters, including Monitoring and Scylla Manager
  • Automate Scylla Cluster operations on K8s
  • Available on and tested with managed K8s providers
