Hibernate is the de facto standard persistence framework for traditional Java database applications. Now, EclipseStore was built to be the Java persistence for containerized microservices and serverless functions. EclipseStore follows the system prevalence architectural pattern. The engine enables seamlessly storing any Java objects of any size and complexity transaction-save into cloud-native blob stores such as AWS S3 or any other binary storage. ACID transactions are journaled and deltas of the system state are regularly saved to disk. To reduce startup time and run also with a small RAM capacity of under 1 GB, MicroStream provides lazy loading. With Java Streams API, queries are executed in memory in microseconds - way faster than comparable JPA queries. Implementing is simple. There are no requirements for the entity classes, no annotations, interfaces, or superclasses, just POJOs. Additionally, expensive mappings or any data conversions are eliminated. The core benefits are extremely high performance, simple implementation, running trouble-free with stateless microservices, and reduced cloud storage costs.

Have you ever worked on a project that didn't use any open source tools, libraries, or products? Didn't think so...Using open source has been such an integral part of our daily work life that we don't even think about it. We just expect it to be available, secure, stable, and bug-free. But how many of you are actually contributing back to an open source project? This session will go through a couple of the aspects to consider when you are embarking on your open source journey. We will look at different kinds of open source projects, and what the open source foundations bring to the table.

About JCON WORLD ONLINE 2023
JCON WORLD ONLINE 2023 is the big international ONLINE Java community conference organized by the Java User Group Oberpfalz in cooperation with JAVAPRO Magazine. Java is our profession and JCON is our passion and a lot of fun. We love to provide Java developers with a spectacular 100 % live conference open to the entire Java-User-Group communities world wide.
Last year, more than 2,600 participants from 77 countries and six continents had joined JCON-ONLINE 2022.
The 8th JCON edition is presented as an online live conference for the third time. All sessions will be streamed live and recorded.
Focus on Core Java & Cloud-Native Java
JCON traditionally focuses on Core Java, Serverside Java, APIs and Frameworks because that’s what we as Java developers work with every day. However, the main topic will be Java-Cloud-Native and Microservices, because this is the future of Java and a must-have for Java developers.

Motivation
We love Java. That’s why we want to bring together Java developers from all over the world. To learn, to connect, to have fun. The feedback we receive proves us right and motivates us to keep going.
Team
JCON is a team effort and a conference by developers for developers. The JUG Oberpfalz does the heavy lifting in organizing everything. But the heart of the conference are our speakers with their sessions.
Community
We often work in completely different branches, but Java is our common denominator and connects us all. Over the years, not only acquaintances but friendships have formed on account of JCON!
