Experimental Features

Schema Changes using Raft

More Robust Tombstone Garbage Collection

ScyllaDB Sizing Up vs. the Competition

ScyllaDB V and the Days Ahead

  • Flexible topology changes — concurrently adding, replacing or removing more than one node at a time from a cluster
  • Elasticity via auto-scaling — reliable, fault tolerant, fast automatic cluster scaling
  • Replacing gossip with Raft — allow faster, more consistent topology changes
  • Strongly-consistent tables — moving from Paxos-based lightweight transactions (LWT) using 3 round trips to fast, Raft-based operations using 1-round trip
  • Tablet partitioning — allows for finer control, better data distribution and load balancing, and easier management of data — faster resharding and cleanup
