In this intensive 4-hour ONLINE course, we will deep-dive into developing ultra-fast in-memory database apps and microservices with EclipseStore. EclipseStore is the very first Java persistence (engine) that enables you to persist any Java object-graph or single subgraphs into any data storage natively. This means any object graph can be persisted as it is in RAM. The EclipseStore approach is fundamentally different from the traditional RDBMS/NoSQL DB-server programming model:
Only 1 data model – just POJOs
No more dealing with DB-specific data models (tables, column-store, JSON, key-value, DB-specific graphs/objects) – which are actually incompatible with object-graphs we use in Java
No more expensive mappings at all
No DB-specific query language, no more classic selects, just using getter
Object-graphs in RAM are used as an incredibly fast pure Java in-memory database which is a kind of multi-model data structure because ANY Java type can be used such as collections. Queries: By using Java Streams API, object graphs can be searched in microsecond query time – up to 1000x faster than comparable traditional database query time and even up to 100x faster than reading data directly from a local JPA cache. An additional caching framework such as EHcache is not required anymore. The end result is an ultra-fast pure Java in-memory database app or microservice having its own superfast persistence. EclipseStore itself is a tiny Java API that can be included into any Java project easily via Maven. It runs on the server, on desktops, within containers, with GraalVM native images as well as on Android. MicroStream is also part of popular microservice frameworks such as Micronaut and Helidon, and well integrated with Quarkus and Spring Boot.
