Distributed Computing

Our goal is to choose an appropriated distributed / persistence architecture and technology for the challenge.

Prerequisites

Java EE knowledge or attendance at the Bootstrap workshop. Java EE Architecture workshop attendance or comparable skills are recommended.

Goals / Topics

CAP and FLP explained

The foundation, or dissecting the Amazon's Dynamo: Consistent Hashing, Vector Clocks, Merkle trees, Gossip and Read Repairs

NoSQL inside out: why we sometimes have to use it

JPA / RDBMS limitations and solutions

Work stealing, leasing with and without JavaEE

Persisting objects and structures with and without JPA

Impact of Java 8 and Lambdas on JavaEE architecture

Serialization, Externalization and optimizations

Binary protocols vs. HTTP and REST

Object oriented vs. record based persistence

Why home-grown persistence framework implementation is challenging (impossible?)

Introduction to Java EE with focus on persistence

JPA usecases, samples and scenarios

Column and row based stores

What is map-reduce? Samples and use cases.

Domain Driven vs. Service Oriented applications

Integration of NoSQL databases

Cassandra

Oracle NoSQL Database (KV Store)

Distributed and persistent caches

Infinispan (JBoss Cache)

Hazelcast

Principles: ACID, BASE, Consistent Hashing, Copy On Write, Lazy / Eager Loading, Optimistic / Pessimistic Locking

JPA features and caveats

Queries, mapping, and relations

Typesafe vs. "fluid" schemas

Schema and database evolution

Clustering, replication, distribution and invalidation

Caching strategies and implementations

Normalization vs. denormalization and redundancies as best practice

Declarative vs. programmatic queries

Performance and memory optimizations

JPA in managed and unmanaged environments

Unit- and Integration Testing with and without mocks

Persistence Patterns

Interesting, but proprietary vendor extensions

New Java EE 7 Features

...prepare some questions!

In this advanced workshop we will code the samples, not a whole end-to-end application. I will also prepare some samples in advance. As a reference, you will get a GIT repository with all samples and solutions, as well as prepared sample applications. Also a GIT repository is going to be used throughout our course, so you will be able to synchronize your projects at any time. (ZIP snapshots will be available as well in nearly real time:-))

You will need a modern developer laptop with pre-installed JDK 1.7, GIT-client, and ideally Maven 3 to get the most from this workshop. We will install the rest of the environment together in the first 10 minutes.

We will spend 60% of the time with code and the remaining part discussing best practices, hacks and workarounds.
