NoSQL database supplier Couchbase says it is tweaking its key-value storage server to hook into Fusion-ios PCIe flash ioMemory products – caching the hottest data in RAM and storing lukewarm info in flash. Couchbase will use the ioMemory SDK to bypass the host operating systems IO subsystems and buffers to drill straight into the flash cache.
Can you hear it? It’s starting to happen. Can you feel it? The biggest single meme of the last 2 years Big Data/NoSQL is mashing up with PCIe SSDs and in memory databases. What does it mean? One can only guess but the performance gains to be had using a product like CouchBase to overcome the limits of a traditional tables/rows SQL database will be amplified when optimized and paired up with PCIe SSD data stores. I’m imagining something like a 10X boost in data reads/writes on the CouchBase back end. And something more like realtime performance from something that might have been treated previously like a Data Mart/Data warehouse. If the move to use the ioMemory SDK and directFS technology with CouchBase is successful you are going to see some interesting benchmarks and white papers about the performance gains.
What is Violin Memory Inc. doing in this market segment of tiered database caches? Violin is teaming with SAP to create a tiered cache for the HANA in memory databasefrom SAP. The SSD SAN array provided by Violin could be multi-tasked to do other duties (providing a cache to any machine on the SAN network). However, this product most likely would be a dedicated caching store to speed up all operations of a RAM based HANA installation, speeding up Online transaction processing and parallel queries on realtime data. No doubt SAP users could stand to gain a lot if they are already invested heavily into the SAP universe of products. But for the more enterprising, entrepreneurial types I think Fusio-io and Couchbase could help get a legacy free group of developers up and running with equal performance and scale. Which ever one you pick is likely to do the job once it’s been purchased, installed and is up and running in a QA environment.
