Chapter 2. Installing VoltDB

VoltDB provides all the transactional consistency and durability of a SQL database, plus best-in-class performance and throughput due to its innovative in-memory design and architecture. The VoltDB software comes as pre-built distributions. This chapter explains the system requirements for running VoltDB, how to install and upgrade the software, and what resources are provided in the kit.

2.1. Operating System and Software Requirements

The following are the requirements for developing and running VoltDB applications.

Table 2.1. Operating System and Software Requirements

Operating System

VoltDB requires a 64-bit Linux-based operating system. Kits are built and qualified on the following platforms:

  • Red Hat (RHEL) version 8.6 and later

  • Rocky Linux version 8.6 or later

  • Ubuntu versions 20.04 and 22.04

  • Macintosh OS X 11.0 and later (for development only)

CPU
  • Dual core1 x86_64 processor

  • 64 bit

  • 1.6 GHz

Memory4 Gbytes2
Java3

VoltDB Server: Java 11, 17, or 21

Java and JDBC Client: Java 8, 11, 17, or 21

Required Software

Time synchronization service, such as NTP or chrony4

Python 3.9 or later

Recommended Software

Eclipse 3.x (or other Java IDE)

Footnotes:

  1. Dual core processors are a minimum requirement. Four or eight physical cores are recommended for optimal performance.

  2. Memory requirements are very specific to the storage needs of the application and the number of nodes in the cluster. However, 4 Gigabytes should be considered a minimum configuration.

  3. VoltDB supports JDKs from OpenJDK or Oracle.

  4. Time synchronization services minimize the time difference between nodes in a database cluster, which is critical for VoltDB. All nodes of the cluster should be configured to synchronize against the same time server. Using a single local server is recommended, but not required.
