eXtremeDB Benchmarks

Designed specifically as an in-memory database system, not an afterthought.

Learn why this matters.

Embedded & Real-time Systems

The eXtremeDB in-memory database system was designed specifically for use in resource-constrained, mission-critical and safety-critical embedded systems.



eXtremeDB enables the developer to easily combine both database paradigms – in-memory and on-disk – in a single database instance.

Embedded and/or Client/Server

Fast, flexible, platform independent eXtremeDB is data management wherever you need it, and can be deployed as an embedded database system, and/or as a client/server database system.

eXtremeDB is fast, flexible database management wherever you need it. Learn more.

Hybrid In-memory and/or Persistent

Combine both database paradigms – in-memory and on-disk – in a single database instance. Specifying one set of data as transient (managed in memory), while choosing persistent storage for other record types, requires a simple database schema declaration.

Learn why starting with an in-memory database makes for a better hybrid system.

White paper: Database Persistence, Without The Performance Penalty

Some applications require higher data durability than in-memory storage provides. What if DRAM could be made persistent? AgigA Tech’s AGIGARAM non-volatile DIMM (NVDIMM) delivers that capability. McObject benchmarked the eXtremeDB In-Memory Database System using AGIGARAM as storage, including “pulling the plug” mid-execution, and comparing the NVDIMM to transaction logging as a solution for data durability/recoverability. This paper presents the benchmark tests and results.

White paper: Will the Real IMDS Please Stand Up?

In-memory database systems (IMDSs) have changed the software landscape, enabling "smarter" real-time applications and sparking mergers and acquisitions involving the largest technology companies. But IMDSs’ popularity has sparked a flurry of products falsely claiming to be in-memory database systems. Understanding the distinction is critical to determining the performance, cost and ultimately the success or failure of a solution. This white paper examines specific products, seeking to answer the question, “is it really an in-memory database system?”

In addition to unique features like Active Replication Fabric™, no other database management system offers such an extensive combination of features for developers to choose from.

Hybrid data storage

Unlike other IMDS, eXtremeDB can combine the strengths of on-disk and in-memory database systems. In other words, eXtremeDB databases can be all-in-memory, all-persistent, or have a mix of in-memory tables and persistent tables with a simple database schema. This unparalleled flexibility enables developers to tailor data management in order to optimize applications for speed and persistence. System developers can make intelligent trade-offs between performance, cost-efficiency, power consumption, and physical space-conserving data storage hardware.

Learn why starting with in-memory database system allows for improved performance.

Active Replication Fabric

Active Replication Fabric offers reliable IoT database management by solving key challenges for developers. eXtremeDB offers bidirectional replication, multi-tier replication (e.g. edge-to-gateway-to-gateway-to-cloud), compression to maximize limited bandwidth networks, and more.

Row & Columnar Flexibility for Time Series Data

Time series data management systems require large volumes of information to be available continuously. eXtremeDB excels in this capability. eXtremeDB for HPC implements columnar data layout for fields of type ‘sequence’. Sequences can be combined to form a time series, ideal for working with tick streams, telemetry, and other sequential data. This technology supports database designs that combine row-based and column-based layouts, in order to best leverage the CPU cache speed. Learn how.

eXtremeDB HA and Cluster

Sharding allows for elastic scalability, and leverages the processing power, memory and bandwidth of multiple hardware nodes. Each database shard can have one or more backup (replica) copies. Cluster is McObject’s distributed real-time database system. It manages databases across multiple nodes, enabling two or more servers to share the workload. It dramatically increases available net processing power, reduces system expansion costs, and delivers a more scalable and reliable database solution. High Availability (HA) enables deployment of two or more synchronized databases within separate hardware instances using communication channels implemented over standard or proprietary protocols. Sharding is a core feature of eXtremeDB. Cluster and High Availability, all of which are offered in a separate add-on module. Here we compare and contrast Sharding, Cluster and High Availability.
