The last of the 4 part BigData trends. This post covers the role of in-memory analytics and some tools that are being used.
What is In-Memory Analytics?
To put it simple: Performing analysis on the memory/RAM. Flash memory’s price is decreasing and the RAM can store Terabyte-size datasets. And since 64 bit processors can address up to 16 exabytes of data , in memory analytics is becoming more affordable by the year.
Why do we need it?
Consumerization is the key for unlocking BI data. Gartner research has concluded that for a successful BI and Big Data implementation consumerization of data would be very important. In memory analytics provides the capability to perform analysis on terabytes of data.
More accessible data would lead to more analysis performed by the business users. Of the 9 emergent technologies impacting BI the most, five are consumer-behavior-driven and one of the key technology is “In memory analytics”.
Gartner : “In-Memory analytics will have an industry impact comparable to web and cloud”
Drivers for In-Memory Analytics:
– Declining memory prices
– 64-bit computing
– Fast queries against big data and improved response time on analytical applications
– Less need for aggregates and low latency application messaging
– Real-time end-user analysis and enabling self service BI
– Detecting correlations/patterns in realtime
– Running OLTP and OLAP application in the same physical dataset.
SAP HANA and Oracle Exalytics ( Couple of in-memory analytics solutions available today )
Both products provide a platform for in-memory database and a slew of tools and software for creating analytical processes and process terabytes of data in a flash.
“SAP HANA enables businesses to make smarter, faster decisions through real-time analysis and reporting combined with dramatically accelerated business processes. Lack of delay between insight and action turns your business into a real-time business.”
