Beschreibung

Flash memories have been in widespread usage for a while but they have had some performance and reliability problems which have made them unsuitable for long term storage of traditional database data. A new class of memory called Storage Class Memories (SCMs) are emerging which are built using different technologies than flash devices. SCMs fall in between DRAM and traditional disk storage along many dimensions (performance, cost, energy usage, ....). As a result, large SCM-based memory systems will be built. SCMs will permit the sizes of databases managed by MMDBMSs to be very large while being cheaper than those using only DRAM. SCMs may be viewed as disks or as memory from an architectural perspective. Depending on the viewpoint, the implications on DBMS architectures will be very different. In IBM Research, we have been working on multiple projects to understand the implications of SCMs on software and hardware architectures in general and on DBMS architectures in particular. Traditional locking, recovery, storage management and query processing ideas would need to be extended to take advantage of SCMs. In this talk, Mohan will discuss what he has learnt from his investigations and what needs to be further explored. This talk should be of interest to hardware, software, systems and storage people both in industry and academia.
