EclipseStore - Databaseless Java Cloud Native Persistence for Microservices

on YouTube ↗56m

" summary

EclipseStore (formerly MicroStream) ships as a final Eclipse release and serializes live JVM object graphs directly to blob storage such as AWS S3, using stores any Java object to cloud blob stores (S3) and reducing storage costs (250 GB on S3 ≈ $70/year vs ~$3,000 for a managed DB). It provides ACID transactions with journaled deltas, lazy loading to run under ~1 GB RAM and microsecond queries via the Java Streams API, supports replication for stateful microservices, requires only POJOs — no annotations or interfaces, and runs in production today.
