What is RonDB?#

RonDB is a fork of MySQL NDB Cluster, one of the storage engines supported by the MySQL server. It is a distributed, shared-nothing storage engine with capabilities for:

in-memory & on-disk columns
up to 1 PiB storage
online horizontal & vertical storage scaling
online horizontal & vertical compute scaling (MySQL servers)

Being supported by the MySQL server, RonDB is inherently ACID compliant. In-memory data is regularly persisted to disk via a REDO log and checkpoints. RonDB is open-source, written in C++.

Strengths#

RonDB delivers on the LATS properties: low Latency, high Availability, high Throughput, scalable Storage. It is the fastest existing key-value store with SQL support.

Being a fork of MySQL NDB Cluster, RonDB is targeted towards the cloud infrastructure, where flexible resource allocation can give the user a low-cost and highly adaptive solution. Significant work has been placed in making RonDB scalable horizontally and vertically for both compute and storage, which is unique for in-memory, relational databases.

Replication#

	Active-Active	Active-Passive
Synchronous (cross-AZ)	1-3 replicas	-
Asynchronous (cross-region)	n clusters (conflict resolution)	n clusters
