ILT: DA650: Code Evolution, Scale and Workflow
In this 2-day course, you'll build an application that adapts its schema over time to meet evolving business requirements. Learn how to support new use cases without overhauling existing data structures—maintaining both flexibility and performance.
Advanced Training: Code Evolution, Scale and Workflow (DA650)
Overview
In this training workshop, students create an application that evolves its schema over time to support new business needs without needing to transform older data. This is a substantial benefit of dynamic schema in MongoDB, but one developers often fail to take full advantage of. We build a social media service akin to Twitter and Facebook with followers, posts and data feeds. We learn how to model high cardinality graphs and handle changes to tricky fields such as username, various write models for extreme scale, and how to build asynchronous worker tasks to ensure the completion of long-running operations even in the event of application or database failover.
Intended Audience
This training workshop is intended for developers who have completed MDB300 (MongoDB Production Readiness) and who are embarking on a project to build a long-lived, highly-scalable application from the ground up. It will get you off to the best possible start to ensure maximum performance and uptime over the lifetime of the application.
Workshop Objectives
In this training workshop, you will learn how to:
create an adaptable data access layer (DAL) to decouple your objects from your schema
use schema versioning to avoid having to rewrite older records
use schema versioning to support running new and old application versions simultaneously
identify bottlenecks which limit scaling and design schemas capable of managing millions of users
apply caching design patterns to optimize retrieval time
use collection-queues and background workers to complete long running tasks asynchronously
Duration
2 days
