Hidden Pearls for Java Embedded High-Performance Persistence
summary
Compares two embedded Java persistence options: MapDB 3.0.8 and MicroStream. MapDB provides drop‑in transactional maps/lists/queues with on‑ and off‑heap storage, MVCC‑based commit/rollback, and a memory → disk expireOverflow caching hierarchy; it’s single‑maintainer open‑source (Apache) and stable. MicroStream is free but not open source, persists full Java object graphs without standard Java serialization, supports lazy references for partial loading and lacks built‑in transactions (MVCC can be layered on). Notes backup as simple folder copy and emphasizes serialization attack surface, recommending security payload testing and Artifactory/X‑ray for governance.
