eXtremeDB

What eXtremeDB is

eXtremeDB is McObject’s database system for embedded devices and applications, with an in-memory design and support for persistent storage. It can use in-memory and persistent storage together within a single database system. Interfaces include native APIs, REST, SQL, ODBC, and JDBC; listed language APIs cover C/C++, Java, Python, C#, Go, and Rust. For time-series data, a sequence data type stores data in columnar form. Distributed options include High Availability, Cluster, and Active Replication Fabric for replication across IoT tiers. Network communications can use TLS/SSL through OpenSSL and wolfSSL implementations. Listed deployment platforms include Android, iOS, Linux, macOS, Windows, API, and self-hosted environments. Technical specifications give maximum database sizes of 4 GB on 32-bit architectures and 18.4 exabytes on 64-bit architectures. McObject says eXtremeDB for HPC is intended for capital markets and other high-performance computing applications. The commercial license is arranged with McObject, and a 60-day trial is available. Evaluation downloads are listed for Linux, macOS, and Windows, with custom trial packages available by request for other platforms. Annual support contracts from McObject’s engineering team include software updates and a 50 percent discount on major upgrades.
