Bigdata and Hadoop

"Raj is a good tutor, he explains everything so clear from basics which makes it easy to catch up with new technology. I can only suggest Raj about case studies, Break Coding practicals into three categories - Basic, Intermediate, Advanced. Teach Basics and few Intermediates in class, and then assign case study for the students which is Intermediate/Advanced or even combination of both. Overall it was a good experience learning Bigdata with Raj. "

"This session was very useful. I didn't expect so much before joining the webinar. But after joining, I felt that I've done a great thing joining the webinar. Basically I'm a good listener. Now, when someone asks about my favourite speaker, then I would say it is Raj Sir. I've learned many concepts from Raj Sir. The sessions were very interesting because of which I used to get up at 8 a.m. in weekends during the webinar just to learn new interesting topics. "

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 .
