What MicroStream does
MicroStream Software GmbH is a Regensburg, Germany-based private company that develops EclipseStore, a Java-native object graph persistence framework that eliminates the traditional database layer by storing complex Java object graphs directly to any storage backend (including cloud object stores like AWS S3 and Azure Blob) and restoring them in RAM without ORM mappings or schema conversions. The product line now spans three Eclipse Foundation open-source projects — EclipseStore (single-node persistence), Eclipse Data Grid (distributed clustering with ACID persistence, indexing, GigaMap, and single-writer architecture), and Eclipse Serializer — with deep first-party integrations into the Micronaut, Helidon, and Spring Boot microservice frameworks, plus a replicated Hibernate second-level cache using Apache Kafka.
The company monetizes through tiered enterprise support subscriptions ($9.99/dev/day Gold, $19.99/dev/day Platin, quote-based Diamond), professional consulting and training services, multi-year update warranties, and a usage-based Eclipse Data Grid SaaS hosted on AWS. Distribution is hybrid: open-source via Maven Central and GitHub for developer adoption, self-serve cloud provisioning for mid-market customers, and consultative enterprise sales for on-premises Kubernetes deployments on AWS, Azure, and Google Cloud.
Founded in 2019 with origins in a 2013 R&D project, MicroStream has raised approximately $2.91M in seed and seed+ funding (led by Bayern Kapital in 2019), maintains a team of 11–50 employees, and is led by co-founder and CEO Markus Kett with Florian Habermann (CTO) and Thomas Schmetzer (CFO). The company positions itself as a performance alternative to JPA/Hibernate, citing peer-reviewed benchmarks showing up to 427x faster performance (University of Bamberg / Springer) and up to 99% cloud storage cost reduction versus database-as-a-service solutions.

MicroStream product offering
Product offeringCore offering
MicroStream builds Java-native data persistence and in-memory data processing software (EclipseStore, Eclipse Data Grid, Eclipse Serializer) that eliminates traditional database and ORM layers by persisting complex Java object graphs directly to any storage. Eclipse Data Grid extends this with distributed clustering for elastic, high-availability Java microservices running on Kubernetes or as fully managed SaaS on AWS.
Product overview
MicroStream (now operating as Eclipse Foundation projects) offers a suite of Java-native data persistence and processing products. The core offering is EclipseStore, a databaseless persistence framework that persists complex Java object graphs directly to storage without ORM mapping. Eclipse Data Grid extends this with distributed clustering capabilities for high-availability, elastic scaling deployments. Eclipse Serializer provides efficient Java serialization. Products are available as open-source (EclipseStore, Eclipse Data Grid, Eclipse Serializer under EPL 2.0) and as enterprise offerings (SaaS on AWS, On-Premises deployment, professional support, consulting, and training services). The portfolio also includes a Replicated Hibernate Second-Level Cache module for enterprise environments requiring cache synchronization across nodes.

MicroStream competitors and assessment
Company assessmentEmerging players
- Aerospike: Real-time NoSQL database with hybrid memory (RAM + flash) architecture for high-throughput low-latency workloads. Competes on speed and cost economics for distributed in-memory data but focuses on NoSQL rather than Java-native object persistence.
- Tarantool: In-memory database and application server with Lua/JVM bridges and persistence to disk or object storage. Shares MicroStream's storage-cost-reduction thesis by persisting to cheap storage while serving in-memory, but targets a different primary language ecosystem.
Broad incumbents
- Redis: Industry-standard in-memory data store with broad polyglot support, massive installed base, and Redis Enterprise offering. Competes in the same in-memory/performance category but serves many more languages and use cases beyond Java microservices.
- Oracle Coherence: Oracle's distributed in-memory data grid for Java enterprise applications. Overlaps with Eclipse Data Grid on distributed Java object caching and persistence, but is part of Oracle's broader middleware portfolio rather than a focused niche product.
Direct peers
- Apache Ignite: Open-source in-memory computing platform offering distributed caches, compute grid, and durable memory. Targets the same Java enterprise use cases for distributed in-memory data processing with persistence and indexing as Eclipse Data Grid.
- Hazelcast: Java-native distributed in-memory data grid with clustering, persistence, and SQL capabilities. Most directly comparable to Eclipse Data Grid as both target Java microservices needing distributed in-memory state with persistence and ACID guarantees.
- GridGain Systems: Commercial offering built on Apache Ignite, providing enterprise in-memory data fabric with hybrid cloud/relational capabilities. Direct commercial analogue to Eclipse Data Grid's enterprise SaaS and support model for distributed in-memory Java workloads.
- ScaleOut Software: Provider of in-memory computing and digital twin streaming platforms, including ScaleOut StreamServer for distributed state. Targets the same enterprise low-latency Java use cases with similar clustering and high-availability architecture.
- Infinispan: Red Hat-sponsored open-source in-memory key-value data grid written in Java. Directly comparable distributed in-memory data store with persistence, indexing, and Kubernetes support targeting enterprise Java applications.
- GigaSpaces Technologies: Provider of in-memory computing and event-driven application platforms for Java. Competes head-to-head on the same high-performance, low-latency, distributed Java data processing workloads that Eclipse Data Grid targets.
