MicroStream is a fundamentally new persistence framework for storing complex Java object graphs, subgraphs, and single objects. In the other direction, it enables loading complex object graphs, subgraphs as well as single objects dynamically and updating the object graph in RAM. With MicroStream database data models become meaningless for Java developers. No more expensive mappings. No more data-type conversion. No more specific query language. Only one data model: Your Java classes without any dependencies (POJOs). No more complex caching layer. No more inconvenient object copies. Simple and clean architecture. Core-Java features instead of database-specific concepts. The end result is a Java in-memory database app or microservice that is ultra-fast. MicroStream is predestined for any database app that needs high performance and especially for microservices having its own persistence. In this live-coding session, you will learn how MicroStream works and how to get started with MicroStream step by step. After that workshop, you will know everything that is important for developing ultra-fast database apps and microservices with MicroStream. And off course, we have enough time for Q&A. Topics: e.g. new features in MicroStream 4, setup, storage targets, configuration, object model design best practice, storing and loading data, lazy-loading, querying complex object graphs with Java Streams API, changing classes and using legacy type mapping / refactoring, backup strategies, providing apps and services access to the persistent data by using REST and GraphQL, using the MicroStream data viewer.
