Session Goals

• Understand:

• When to use EMR?

• Do:

• Start Cluster

• Load Data from S3

• Transform Data

• Unload Data to S3

Draw elements from Gil’s deckPattern

When to use EMR?

• Some Boolean combination of the following:

• Ephemeral clusters

• Batch processing: daily, weekly, etc.

• User Defined Functions (UDF)

• File formats

• TB, PB data sets in S3

• Instant gratification

Let’s Do This!

What do we need?

• Key (.pem file)

• SQL Workbench

What will we do?

• Start Cluster

• Load stock market data from S3

• Calculate Sharpe ratio

• Unload Sharpe ratio results to S3

The Sharpe Ratio characterizeshow well the return of an assetcompensates the investor for therisk taken. Roughly, the higher thebetter.
