Java In-Memory Database-Apps with MicroStream
summary
MicroStream claims to store Java object-graphs natively with a custom serialization engine that reintegrates deserialized objects into the live graph, does incremental backups, and writes to any byte/block target since v4. It exposes store()/storeAll() with transactional semantics, a background garbage/ file cleanup, and lazy loading with a lazy reference manager that clears unused references — default: lazy references cleared after 30 minutes or when RAM <25%. Benchmarks report 10–20x faster than Java serialization. Current deployment is one JVM per storage; distribution is in progress.
