eXtremeDB combines on-disk and in-memory data storage in a single embedded database system, so developers can optimize applications for speed and persistence, giving you flexibility to prioritize between performance, cost, power, and space-conserving storage options.  Offering native and SQL APIs for C, C++, C#, Java and Python.

eXtremeDB for HPC hybrid persistent and in-memory database can be deployed as an embedded database system or elastically scalable client/server distributed database (read more about sharding).  Extend the power of eXtremeDB with Cluster and High Availability, an SQL API and stored procedures in Lua, Python or C/C+.

The eXtremeDB for IoT SDK is a unique new IoT development toolkit offering standard eXtremeDB  Active Replication Fabric to allow complete oversight over network connection losses, as well as support on all platforms from edge to cloud. Built on a proven data management solution, eXtremeDB is found world-wide in systems ranging from nuclear power plants to networking equipment to stock market trading platforms.

Winner Best in Show award in the Development Tools and Operating Systems category in its debut at the IoT World Santa Clara May 2019.

Extend the power of eXtremeDB with distributed database capability (Sharding, Cluster and High Availability), and an SQL API.  

eXtremeDB Cluster and High Availability

Cluster is McObject’s distributed real-time database system. It manages databases across multiple hardware 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 synchronization of two or more databases within separate hardware instances using communication channels implemented over standard or proprietary protocols.

eXtremeDB SQL

eXtremeSQL is McObject’s high performance implementation of the popular SQL database programming language. SQL can be used directly, or through ODBC or JDBC. eXtremeSQL provides broad coverage of SQL standards, plus eXtremeDB-specific extensions including support for nearly all eXtremeDB native language data and query types, a sophisticated distributed query engine and a library of over 100 vector-based functions for time series analytics.

How is eXtremeDB different?


Hybrid data storage.
  Unlike other IMDS, eXtremeDB databases can be all-in-memory, all-persistent, or have a mix of in-memory tables and persistent tables.

Active Replication Fabric™ is unique to eXtremeDB and 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.  eXtremeDB supports database designs that combine row-based and column-based layouts, in order to best leverage the CPU cache speed.

Embedded and Client/Server.  Fast, flexible 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.
