Alternator, Our DynamoDB-Compatible API

Amazon DynamoDB users can now switch to ScyllaDB without changing a single line of application code. ScyllaDB significantly reduces the total cost of ownership, delivers lower and more consistent latencies, and expands the limitations DynamoDB places on object size, partition size, etc. You can run ScyllaDB on-premises, on your preferred cloud platforms, or on ScyllaDB’s fully-managed database as a service, ScyllaDB Cloud. You are free to access their data as you like, without pay-per-operation fees, and with more deployment options, including Docker and Kubernetes.

Lightweight Transactions

ScyllaDB’s implementation of the Paxos consensus algorithm for Lightweight Transactions (LWT) is far more efficient than Apache Cassandra and other Cassandra-compatible offerings, allowing you better performance for compare-and-set conditional update operations.

Incremental Compaction Strategy (ICS)

ScyllaDB’s unique ICS compaction strategy is an improvement on the default Size Tiered Compaction Strategy (STCS). While it shares the same read and writes amplification factors as STCS, it fixes its doubling of temporary disk usage issues by breaking huge SSTables into smaller chunks, all of which are named an SSTable run. ICS is the default compaction strategy in 2020.1.

CQL Enhancements

ScyllaDB Enterprise 2020.1 also introduced enhancements for the Cassandra Query Language (CQL), to provide more granular and efficient results, from adding new clauses such as GROUP BY and BYPASS CACHE, to enhancements in ALLOW FILTERING (such as multi-column and CONTAINS restrictions), to a LIKE operator to enable searching for patterns in user data.

Built on the Foundations of ScyllaDB Enterprise 2019

After 5,568 commits originating from five open source releases, ScyllaDB Enterprise 2020 has many additional additional features and enhancements since ScyllaDB Enterprise 2019, including:

  • Incremental Compaction Strategy to get the most out of your infrastructure
  • Local (in addition to global) secondary indexes provide you data flexibility
  • IPv6 support to expanded network address space
  • Encryption at Rest, including local, replicated and KMIP providers
  • Large Cell/ Collection Detector to proactively find problematic anomalies in your database
  • Nodetool TopPartitions to identify hot partitions
  • MC SSTable format for more efficient storage
  • Row-level repair provides a fast, granular anti-entropy mechanism
  • Support for AWS i3en “meganode” servers with up to 60TB/node
  • Improved CQL server admission control
  • Relocatable packages for easy, foolproof installation
  • New deployment options for Debian 10, Red Hat Enterprise Linux 8, CentOS 8
