McObject Publishes White Paper on Database Durability and Recoverability
McObject published a white paper about solutions for database durability and recoverability. The technical paper shares tests using the eXtremeDB IMDS and on-disk DBMS technology, along with commercially available hardware including Fusion ioDrive2 NAND flash memory from Fusion-io. The title of the article is: Seeking Fast, Durable Data Management: A Database System and Persistent Storage Benchmark.
Seeking Fast, Durable Data Management White Paper
In-memory database systems (IMDSs) eliminate much of the performance latency associated with traditional on-disk database management systems (DBMS’s), but some applications require a higher level of data durability (i.e. an ability to recover if someone “pulls the plug” or otherwise disrupts volatile memory). As a solution, IMDSs offer transaction logging, in which changes to the database are recorded on persistent media. But critics object that logging re-introduces the storage-related latency that builds slowness into on-disk DBMSs.
Will an IMDS with transaction logging outperform a traditional DBMS? Will type of storage — hard disk drive vs. SSD vs. state-of-the-art memory-tier device — affect any performance difference? McObject’s benchmark report answers these questions with tests using IMDS and on-disk DBMS technology. It also examines the impact of transaction length (long vs. short) on database system performance and the interplay of storage device type with this effect.
