Persistence strategies for aggregates: exploring the trade-offs
This is a hands-on lab with limited capacity.
There are many ways to persist an aggregate and there is no one-size fits all approach to this task. This workshop introduces six different approaches for storing aggregate data in a datastore and explains the pros and cons of each approach.
Some of them are not invasive to the aggregate’s implementation but come with a cost, others may leave their marks for the sake of simplicity.
The six strategies that we will discuss are:
- Plain SQL
- O/R Mappers (flavors: Annotations and XML)
- Document Databases
- Memento Pattern
- Same package, different (Maven / Gradle) Module
- Event Sourcing
Each of these examples will be showcased in a hands-on manner with Java code examples and come with a thorough exploration of their advantages and disadvantages.
The workshop aims to enable you to navigate the tradeoffs when making design decisions about the persistence approach for your aggregates.
