Predictable Real-time Data Management Over Persistent Storage Media
A white paper written by Andrei Gorine, Chief Technical Officer, McObject LLC, and Thom Denholm, Technical Product Manager, Tuxera.
Abstract – Embedded designs with predictable performance requirements are subject to timing constraints – their response to events must fit within timeframes that are known in advance. The growing complexity of real-time systems translates to more, and more complex, data to manage. Further, the volume of data may be such – or the regulatory need for data retention may mandate – that persistent media be introduced. However, hard-disks, NAND flash, and SSD introduce unpredictable latency. How can timing constraints be met in this case?
“The inherent unpredictable delays introduced by the flash erase operations and bad block management can be mitigated by the database kernel.”
