Designing Great Java In-Memory Object Models
summary
EclipseStore makes the in-memory Java object graph the source of truth and removes ORM mapping, using a storage manager (configurable channel count — demo uses two channels) and pluggable type handlers for JDK 8/17; a bookstore demo generates data with CH Faker, persists it, and reloads successfully. Models use segmentation (lists for small sets, maps for thousands to tens of thousands, extra segmentation or lazy-loaded year buckets for time-series or hundreds of thousands+). Concurrency uses ReentrantReadWriteLocks; deletion is by removing references or soft-delete flags; full-text search integrates Lucene.
