In-Memory Databases vs Intel NVMe NUMA

By | Blog, Database Technology Trends, SAP HANA, Sybase | No Comments
For the past few years, the hot topic for database vendors was the in-memory database. The general belief was and maybe still is, that server memory is getting cheaper and density will continuously improve. For the most part, this has been the case, maybe not as extreme as predicted. However, the data storage needs for databases increased at a much faster pace during the same time, which created another problem. Going beyond 1TB of memory in a single server will quickly become very expensive. A 1TB database used to be called very large. This attribute is now applied to the 5-10 TB databases servers. In-memory databases are needed where read and write performance are equally important. Traditional databases improve read performance by caching data in memory, but there is no way to improve write performance. To be ACID (Atomic, Consistent, Isolated and Durable) compliant, data must be written to persistent storage. An in-memory database achieves this by writing every transaction in parallel to a high-performance storage. In many cases this is a flash drive on the PCI bus or a SSD drive. But every write action must be stored away from Memory (RAM) to be ACID compliant. There are many (more…)
