Big Data is like Tourism But if you aren’t an expert,

you can’t make the most of itIt seems easy to do

Struggle to analyze Big Data

Deep analytics

Libraries!

We need libraries...

Query languages

Write your own MR/RDD/Transformations

… comprehensive ones!

Say it with memes!

When you doDeep analytics in small data

using R and CRAN packages

When you dodeep analytics in BIG data

using R and CRAN packages

When you try to program it using MapReduce

When you try to program it using Apache Spark /

Apache Flink

When you try to use a library scalable to large data sets

Can’t we do it better?

- Make it similar to normal R programs.

- Hide complexity.- Make file manipulation easier.- Part of the computing in the

cluster and part of the computer in the client.

Our approach

Our approach

Behind the scenes: Before

Behind the scenes: After

Without writing significantly different code

Competitive or even faster than R native code in small data

And it scales

Some relevant findings

- Transmission time was not significant.- Stratosphere/Flink was competitive in highly

iterative programs.- We were not able to do it keeping the code

100% the same.- Ensemble scenarios are the most exciting

ones.

4 Takeaways from this talk

- We still need to bring Big Data to the right people in the right place.

- We need comprehensive libraries.- We need to move data back and forth.- Use a syntax that the users are familiar with.

That’s all!- Have you found this talk interesting?
