Road Map

ScyllaDB is an open source company that is committed to open innovation and transparency. Though our plans are always changing in response to customer input, market evolution, and development constraints, this page is a point-in-time snapshot of our current efforts. You can see our actual progress through the open source Scylla project on GitHub including a public project issue tracker. You are welcome to add feature requests and vote for your favorite issue.

The following roadmap is intended to outline general product direction and should not be relied upon in making purchasing decisions. The content is for informational purposes only and may change. In general, we will follow Cassandra upstream and adopt any sane feature developed, as well contributing new features.
Selected features from 2.x will be be delivered as part 1.x releases.

Scylla 1.x

  • Administration and management hardening
  • SStableLoader support for Cassandra 2.2 and Cassandra 3.x sstable format
  • CQL compatibility with Cassandra 2.2 and Cassandra 3.x
  • Use DNS resolution for ip/seed
  • Debian packages

Scylla 2.0

  • Materialized View (MV) and MV base Sec Index
  • Counters
  • Lightweight Transactions
  • Incremental Repair
  • Support for Cassandra CQL Binary v4
  • Time Window Compaction Strategy

Scylla 2.1 and beyond

  • Database enhancements – There are several fascinating ideas we plan on adding.
  • Horizontal expansion – We have a high speed I/O engine that can scale up and out with excellent HA/DR. Why stop with the CQL protocol? There are many interesting additional protocols to go after.
  • Vertical expansion – Integrate with analytics and search.

Cassandra Compatibility

Scylla is a drop-in replacement for Apache Cassandra 2.1.8, supporting both the data format (SSTable) and all relevant external interfaces. More below.
With upcoming versions, Scylla will support all features of Cassandra 2.2.x and 3.0.x releases. Features beyond 3.0.x will be considered, with attention to continuing support for Cassandra external interfaces.
