What eXtremeDB is

eXtremeDB is an in-memory database system designed for embedded devices and applications. It can combine in-memory and persistent storage within one database system, and offers native APIs alongside REST, SQL, ODBC, and JDBC interfaces. Listed language APIs include C/C++, Java, Python, C#, Go, and Rust. A sequence data type provides columnar storage for time-series data. Distributed options include High Availability, Cluster, and Active Replication Fabric for replication across IoT tiers. Network communications can use TLS/SSL with OpenSSL or wolfSSL. Technical specifications list maximum database sizes of 4 GB on 32-bit architectures and 18.4 exabytes on 64-bit architectures. McObject offers an annual support contract from its engineering team that includes software updates and a 50 percent discount on major upgrades. The commercial license price is available by request, and a 60-day trial is listed. Linux, macOS, and Windows evaluation downloads are available; custom trial packages can be requested for other platforms. McObject describes eXtremeDB for HPC as intended for capital markets and other high-performance computing applications.
