Elasticsearch Scala Config

This is a simple elasticsearch scala config.

SBT Config

Add the following dependency:

"com.sksamuel.elastic4s" %% "elastic4s-http" % "6.5.1"

Create the pemfile using aws-cli:

$ aws ec2 create-key-pair --key-name rodrigo-hernandez-mota-ds-dev --query 'KeyMaterial' --output text --region us-west-2 --profile ds-dev > rodrigo-hernandez-mota-ds-dev.pem

$ chmod 400 rodrigo-hernandez-mota-ds-dev.pem

Create the pemfile using aws-cli:

$ aws ec2 create-key-pair --key-name rodrigo-hernandez-mota-ds-dev --query 'KeyMaterial' --output text --region us-west-2 --profile ds-dev > rodrigo-hernandez-mota-ds-dev.pem

$ chmod 400 rodrigo-hernandez-mota-ds-dev.pem

Tree Traversal Exercise

Given a tree-like structure like:

          3  
        / | \
       1  5 10   
      /  / \  \
     6  1   4  5

The enrollment-database contains data resembling the following:

student

id	first_name	last_name	gender	gpa	age
1	Amelia	O'Sullivan	female	3.7	20
2	Rachel	Stevens	female	3.5	25
3	Sarah	Dunn	female	3.2	23
4	Liam	Baker	male	3.3	24
