"If you work at Amazon, you cannot use and refer to this document because of the copyright violation issues." --> This is really interesting. Does anyone know the background on this? Has anyone else seen this someplace else?
Edit: maybe the confusion here is about what “storage layer” means here. The physical row encoding is still the same. What’s different in Aurora (there are white papers on this) is how the WAL records get applied directly to encoding aware distributed as opposed to separately syncing the heap storage to disk.
