Forget abt general niche solution Simple Historical Data Loading with Update is not possible though with Hive 14 ACID is started but at least 2–3 years it will take . Currently of all the hypes the process is drop org table , merge with delta with some non performant sql with unions and then re-create the table . Then there is that serial surrogate key generator . so if i have say 100 TB database and just to load say 50–60 GB delta i will have to drop at least 30–40 Tb and re-create it again ( Leaving aside the Fact tables ) . Also what abt data correction ad hoc . With index and partition also it is heavy duty . for datat mining also any day any time still and near future traditional dbs will beat hadoop stack in performance as well as functionality . read less

Hello, I am Ali from Hyderabad, and I am into Telecom field as a Network Performance Engineer from the past 3 years, and as I don't find any growth in Telecom Field due to stability I am thinking to switch into IT field. And so far whatever I have researched I found Big Data is the demand in IT sector. 1. Can a non-IT guy with no programming/coding knowledge can step into Big Data? 2. How much scope does Big Data have or for how much years can we except Big Data around? 3. If I opt the course into your institute, will there be any real-time exposure during the course? 4. Can I easily get a job into Big Data as I am a non-IT person? And any experts or who have already taken course from any Institution and got helped in getting placements, please do suggest me which would be the best.
