The exponential growth of data combined with the need to derive real-time business value is a critical issue today. An event-driven data mesh can power real-time operational and analytical workloads, all from a single set of data product streams. With practical real-world examples, this book shows you how to successfully design and build an event-driven data mesh.
Building an Event-Driven Data Mesh provides:
Practical examples of event and event stream design, including recommendations A clear understanding of how events relate to systems and other events in the same stream and across streams A realistic look at event modeling options, such as state, delta, and command type events, including how these choices will impact your data products Methods for handling events at scale, including multitenancy Best practices for privacy and regulatory compliance Advice on handling eventual consistency and building multitenancy solutions and asynchronous communication Practical tips for iteratively building your own event-driven data mesh, including hurdles youâ??ll encounter, possible solutions, and how to obtain real value as soon as possible Solutions to pitfalls you may encounter when moving your organization from monoliths to event-driven architectures
Building an Event Driven Data Mesh 1st Edition Table of contents:
1. Introducing Event Streams for Data Communication
The Case for Event Streams and Event-Driven Architectures
A Brief History of the Operational and Analytical Plane
The Operational Plane
The Difficulties of Communicating Data Between Operational Services
A short opinionated history of big data – Hadoop, Data Warehouse, Lakes, and Analytics
The Organizational Impact of Schema on Read
Problem 1: Improper Data Model Boundaries
Problem 2: Ownership is spread across multiple teams
Problem 3: Do-it-yourself & Custom Point-to-Point Data Connections
Bad Data: The Costs of Inaction
One more problem to solve: Unifying analytical and operational workflows
How Do We Resolve All Of These Data Issues?
Common Objections to an Event-Driven Data Mesh
Producers cannot model data for everyone’s use cases
Making multiple copies of data is bad
Eventual Consistency is too difficult to manage
Chapter Summary
2. Designing Events
Introduction to Event Types
State Events with Event-Carried State Transfer
Current State
ECST events with Before/After State
ECST Event Definition Recommendations
Action Events (the type previously favored by ephemeral message brokers)
Event Sourcing and Its Incorrect Usage Between Domains
1) There is an Infinite Set of Possible Event Types
2) The Logic to interpret the events must be replicated to each consumer
3) These events map poorly to event streams
4) Inversion of ownership: Consumers put business logic into the producer
5) Inability to maintain historical data without excessive complications
Action event takeaways
Measurement events
Hybrid Events – State with a bit of Action
Notification Events
