Computational Storage - Delta Chain for updatable objects in OxDelta Chains in OX
One of the limitations to Ox Block is that everything has to be aligned to the sector size on the SSD, 4 kb. Another limitation is that in place updated are not allowed on SSD’s in general, but using an entire erase and write cycle might be wasteful if the update is minimal. A solution to both of these problems would be to implement a system that manages the difference in an update to an already written page. An idea for this system is a so called delta chain, that keeps track of the difference in updates to a page and stores them as deltas. Then it only writes to the original page at a convenient time. There is an abundance of questions that need to be answered before such a system can be implemented. Some of those questions are: • What is a delta? • How is a delta stored? • When is the delta chain applied to the original page? • How is the delta chain applied to the original page?
