EclipseStore Fundamentals Training | Christian Kuemmel (EN) 1211

Описание: In these intensive 4-hour online courses, we will deep-dive into developing ultra-fast in-memory database apps and microservices with the EclipseStore persistence framework. After these courses, you will be able to build ultra-fast in-memory database applications with EclipseStore. The EclipseStore Advanced training courses are based on the EclipseStore Fundamentals training.

EclipseStore questions and answers

EclipseStore is the first Java persistence (engine) that enables you to store any Java object graph of any size and complexity persistently in any data storage. Therefore, your Java objects are serialized in a binary format, and binaries are stored directly on disk or in a cloud object storage like AWS S3. Expensive mappings or data conversions are eliminated. The EclipseStore approach is fundamentally different from the traditional database server (RDBMS/NoSQL) 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 incompatible with the Java object model
no more expensive (object-relational) mappings or data (JSON/XML) conversion at all,
no DB-specific query language, no more classic selects, just using getter.

Your Java object graph in RAM is a kind of multi-model data structure because it allows you to use any Java type and connect them freely to crate any data structure of any complexity. Using inheritance and circular references is also trouble-free. Your object graph becomes an extremely fast in-memory database. You can search and filter in microseconds by using Java Streams API, which is up to 1000x faster than comparable traditional database queries and even up to 100x faster than retrieving data directly from a local cache. As data is kept and managed in RAM, using an additional cache such as EHCache is not required anymore. The result is an ultra-fast pure Java in-memory database application. EclipseStore is also a predestined light-weight persistence for microservices that need persistence. EclipseStore is just a tiny Java library you can download and include in any Java project easily via Maven. It runs wherever a JVM is available, on the server, desktops, in containers, with GraalVM native images as well as on Android. The only requirement is Java 11 or later. EclipseStore is also well integrated with popular microservice frameworks such as Micronaut, Helidon, and Spring Boot.
