My tella boss saying hadoop will cool down after few years .....intially everyone will be excited to implement the hadoop ecosystem ..after few years when every hadoop environment gets big with data...nobody knows how to do performance tuning...bcoz its opens source...and all will be back to regular rdms....so he said ..six back relax and enjoy the freak show..

Yes, Currently its a freak show and most of market is driven by hype. Many companies are yet to utilize full potential of Big data but its just a matter of time

We already have teradata which can handle >10tb of data efficiently infact in my current workplace TD db is >8tb. As you stated RDMS is definately not the answer for Big data but newer teechnologies are emerging to support vast amount of data.

But i think there is limit for teradata right? How many transactions it can handle if it is used in a application like twitter ?

Hmm consultancy vadi suggestion baa adhi...bifdata ante enti...? Em tools untay andhuloo

Inka Cognos pattukuni ennallu oogutavu... move on... Edanna BifData tool nerchuko..


Like Splunk...

Reporting e ante... Tableau & MSTR better options

[athapurbaba]

So a a tools lo coding untundha bhayya ..? Mongo cassandra etc lo

Holda..Holda..dont scare the kids by telling they need to write...mappers ..reducers and rappers....nobody is writing rapers from scratch these days...everthing is customization of third party tools fo hadoop..

Learn hadoop concepts....i mean..just theory and concentrate on a tool ..like spark, hive,impala,cassandra,mongo..blah..blah...
the first question you will be asked in the interview will be not "what is hadoop"...but "how will you do performance tuning for hadoop environment"...

Splunk Spark BD related tools... UNIX,SQL DWBI Concepts teliste manchidi... Java vast inks manchidi mani mot must.

 

Paina discuss chesinattu ga... I feel like

 

"Big data is like teenage sex: everyone talks about it, nobody really knows how to do it, everyone thinks everyone else is doing it, so everyone claims they are doing it..."

 

Maa company kooda use chestundi... just to process the raw data like data generated by social media etc.,

 

At the end of the day CXO level reporting/analytics ki Market lo unna tools e gati....

Technically it all comes down to level of tuning and hardware (i.e use of 4gb/s fibre channel), In our case db is updated with approx 50m records a day. As far as twitter goes it stores a massive transactions of around 250M a day using a customized version of mysql with the combination of in-house developed storage solution called Manhattan
