Caching and serving blobs from S3, and Building a high throughput rest API

  • Jan 15, 2014 · 7:00 PM
  • Audax Health

We've got two great talks lined up for the January meetup! Everyone from beginners to experts will find something valuable in these two talks highlighting experiences with and lessons learned from real world usages of Scala.

Food and drinks will be provided. 

Approximate schedule:  

6:30 - Doors open 
7:00 - General intro 
7:05 - Caching and serving blobs from S3
7:35 - Building a high throughput rest API
8:05 - Social hour 


For the first talk, Jim Fulton, a long-time Python developer, will talk about how he used Scala to create a blob server for an object database.  The talk presents this small application which touches on a number of technologies, including S3, Spray, ZooKeeper, subcut and Akka.  We'll discuss some challenges, including mocking with statically-typed languages, and the power and peril of frameworks that rely heavily on implicits.

For the second talk, Bhaskar Karambelkar, tech lead and senior software engineer for Managed Security Solutions at Verizon Business, will talk about lessons learned in building a Scala+Play+Akka based scalable REST API and taking it to production. He'll be discussing basic design of a scalable API, plus things to watch out for, and best practices when taking such code to production.

Getting here 

Audax Health is located in the Georgetown waterfront building:

3000 K St. NW, Sixth Floor 
Washington, DC 20007

Metro - We are about a 15 minute walk from the Foggy Bottom metro stop on the Blue and Orange line

Parking - Our building has a parking garage ( The entrance is on the river side of K street (under Whitehurst Freeway), between Thomas Jefferson St. and 30th St. It's a flat $10 after 4PM.

Once you've parked or have arrived at the Washington Harbor complex, our building is the one on the left if you are looking towards the river. The entrance is at street level, to the left of the smaller fountain (if you see Tony & Joes or Sequoia, go up the stairs away from the river and turn right). The doors are locked but we will have someone at the front desk from 6:30 until 8, so just knock.

Here is a link to a map with the parking garage entrance and our building entrance marked:,-77.057446&spn=0.00253,0.004726

Please RSVP if you plan on attending. Thanks!
