McObject is shipping a new release of its flagship Linux-ready in-memory database for real-time applications, including high-availability applications. ExtremeDB 4.0 beta enhances multi-user performance, adds a second native application programming interface (API), and adds support for the KD-Tree database index, used for pattern matching, says the company.
The ExtremeDB maintains a code footprint as small as 50KB, enabling it to run in memory for most embedded applications, thereby improving performance compared to disk-based operation, says McObject. The Linux-compatible software is said to support transactions, concurrent access, and a high-level data definition language. McObject also offers a high-availability version that supports local or distributed replication, with automatic fail-over, and earlier this year it shipped an ExtremeDB version that runs in kernel mode.
