For hard real-time systems
Maximize Database Reliability
Features to look for in a reliable database management system.
Database system reliability encompasses protection from loss of database availability, safeguards on data integrity, and resistant to database corruption caused by application software defects. eXtremeDB was designed from the beginning to maximize database reliability.
Transaction logging provides recoverability. While it might seem that transaction logging re-introduces on-disk storage overhead into in-memory databases (IMDS), McObject’s benchmark tests confirm that an IMDS with transaction logging still outperforms a traditional “on-disk” DBMS performing the same tasks, even when the on-disk database is fully cached.
Non-volatile memory support
Using non-volatile memory as storage, in-memory databases gain durability while keeping high performance. (For more in this topic, please review McObject’s white paper, Database Persistence, Without the Performance Penalty.)
eXtremeDB’s high availability option ensures continuous database operation even in the face of hardware or software failure. eXtremeDB’s HA support includes both synchronous (2-safe) and asynchronous (1-safe) replication, with application-directed failover.
The database runtime implements many verification traps and consistency checks. After application debugging, the optimized version of the eXtremeDB runtime can be used, removing traps and internal checks, and restoring valuable clock cycles. In addition, cyclic redundancy check (CRC) is built into the backup-and-restore feature for in-memory databases, to ensure the database was written in its entirety when saved, and has not been corrupted. Learn more in our online documentation.
An additional benefit of using cyclic redundancy check is to detect unauthorized tampering with the database contents (without going through the eXtremeDB run-time).
