Key Challenges

• New Type Of Database (Cassandra)• New Type Of Deployment (Elastic in the Cloud, Small & Fast on the Desktop)• New Type of Access (REST API, SDKs)• New Type of Learning Curve (Smart Docs & Swagger)

15

Major Milestones & Progress

• 2011 – Usergrid released as first Open Source BaaS• 2012 – Usergrid becomes part of Apigee• 2012 – Apigee ships Enterprise App Services• 2013 – Integrated as Apigee Edge BaaS• 2013 – Usergrid goes to Apache• 2014 – Apache Usergrid 1.0 release!• 2014 – Apigee 127 Developer Kit with Node.js, Volos, and Usergrid• 2014 – Apigee BaaS 2.0 and Usergrid 2.0 Beta

How do you use a BaaS?

17

/users

/groups

/users/me/followers

/restaurants/products/car-washes

/<whatever>

POST /devices/<id>

POST /events

{ “category” : “ads”, “counters” : { “ad_clicks” : 5}}

/users/ed/friends/nate

/users/ed/likes/foods/pizza

GET /restaurants?near=37.803, -122.404

GET /restaurants?ql=name contains ‘pizza’ and within 5m of 39.962,-105.114

POST /users/me/activities

{ “title”: “look”, “location”: …}

GET /users/me/feed

[{ “title”: “Ed ate a slice of pizza”, “location”: …}]

postUserActivity(me, activity)

[client postUserActivity: “me”activity: activityObj]

/token?grant_type=...

/auth/facebook?fb_access_token=…

/users?filter=facebook.first_name eq 'john'

/users?ql=name eq 'john' and facebook.education.school.name contains '...'

New Pieces of the Stack

33

RxJava GuicyFigArchaius

Challenges

• 1.0 Architecture had a number of Cassandra anti-patterns

• Enterprise users wanted to load and query large datasets

• Cassandra moving to 2.0 with CQL3, deprecating Thrift protocol

• Team wanted to leverage new indexing models of Elastic Search

34

New Architectures

• Elastic Search

• Cassandra 2.0+

• Moving most common operations to CQL as the transport

• Archaius and Guice for dynamic configuration management

• Hystrix and RxJava

35

New Architectures: Elastic Search

• Right tool for the job

• Cassandra worked… until it didn’t.

• Well known operationalization characteristics

• Scale-out was well understood for “full text search” use case

36

New Architectures: Cassandra 2.0/2.1

• Still best of breed NoSQL solution for scale

• Off-heap performance improvements

• Failure scenario performance improvements

37

New Architectures: Archaius and Guice

• Properties typing

• Property change polling

• Hierarchical callbacks on changes

• Load from anywhere dynamic sources

• … all via Guice annotations

38

New Architectures: Archaius + Guice = GuicyFig

39

New Architectures: Archaius + Guice = GuicyFig

40

New Architectures: Hystrix and RxJava

• Compose sequences of asynchronous events declaratively

• Circuit breaker pattern for back-off and retry

• Natural fit with complex, asynchronous operations such as graph updates…

41

New Architectures: RxJava Example

42

More Stuff

• Major components are plug-able

• MVCC

• Directed edge graph supports time series and collections

• Chop load testing framework

43

New Open Source Projects Spun Out

• Judo-Chop: annotation based load testing framework

• GuicyFig: combination of Netflix’s Archaius and Google’s Guice

• Modular Cassandra JUnit integration (coming soon!)

44

What’s next?

45

Usergrid 3.0

• V2 API (V3?)

• Subscriptions (standing server-side queries with notifications)

• WebSocket/Server-side Events

• WebHooks

• Data storage management (reporting, limits, etc.)

• Collection management (deletes, copies, etc.)

• Consistency exposed via API(conditional puts, etc.)

• Indexing API

• Queues

• Expanded/pluggable sign-in (more Oauth, LDAP, etc.)
