- What has driven the need to have the term big data?Big data first used in 1997 but refers to just sizeVolume, Variety, Velocity grouped together 2001What do they have in common?They are all difficult to handle with the traditional data stack2011 “Big Data” = 3VsIs variability or velocity big?Not really but big data was a convenient umbrella termShould have called it Awkward DataI’ll never get a job at Gartner
- Big Data is born online. Latency for these applications must be very low and availability must be high in order to meet SLAs and user expectations for modern application performance. Offline Big Data encompasses applications that ingest, transform, manage and/or analyze data in a batch context. They typically do not create new data. For these applications, response time can be slow (up to hours or days), which is often be acceptable for this type of use case. Since they usually produce a static (vs. operational) output, such as a report or dashboard, they can even go offline temporarily without impacting the overall goal or end product.
- Indeed: #2 just after HTML and ahead of iOS, Android, HadoopJasper: Demand for MongoDB, the document-oriented NoSQL database, saw the biggest spike with over 200% growth in 2011.451 Group: Bigger than next 3 or 4 COMBINED; biggest quarter-over-quarter and year-over-year growth (again)
