MicroStream is the team behind the new Eclipse projects EclipseStore and Eclipse Serializer. EclipseStore is a databaseless Java persistence approach. Object-relational mapping (ORM) and even a database is not required at all. EclipseStore is a tiny Java library that runs within your app’s JVM process. It enables to sync any Java object graph of any size and complexity into any cloud object storage such as AWS S3 or into plain files. EclipseStore provides 3 main benefits: 1) high performance: all data operations are executed in-memory by using core Java concepts only - up to 1000x faster than comparable JPA queries. 2) lowest data storage costs in the cloud: cloud object storage is up to 98% cheaper than cloud databases. 3) simplicity - EclipseStore adds persistence to Java. It leads to a simple architecture, implementing, testing, deploying and maintaining is way easier than traditional ORM frameworks. EclipseStore runs also on Android and provides simple to use persistence on mobile, embedded and edge devices. With MicroStream Cluster, we provide a fully managed cloud service for building highly scalable distributed EclipseStore cluster applications. Download: www.eclipsestore.io
